6. I have a requirement that in ultimate thread group , constant throughput value needs to be changed for every 5 mins using beanshell pre-processor. If 0 is given then JMeter will release the same number of users which is defined in the thread group. Thread Group 3. iii. 0 requests/minute is saved as 0. If you set its value as “1. After that, we need to add the constant throughput timer, so first, we need to right-click on sample-> select Timer, and inside we need to click on Constant Throughput Timer and set the constant throughput timer as per our requirement. You can specify the pause in ‘Thread Delay’ field. JMeter: Holding Session for a certain. 1. g. 2. 10 000 requests in one hour is something like 166. Constant Throughput Timer will let you control the flow of requests to be. I am having 5 request inside that. log can be very useful for troubleshooting JMeter-specific issues. A user logs in, goes to the main page, searches for a product, sees. The Constant Timer is self-explanatory: it delays each sampler by a constant Thread Delay value. With 100 threads you will get 50 requests per second. If you choose to add more than one timer to a Thread Group, JMeter takes the sum of the timers and pauses for that amount of time before executing the samplers to. Concurrency Thread Group doesn’t provide the ability to define initial delay, step transition and ramp-down - which the Stepping Thread Group does. Issue: If i run the test, I was expecting the min throughput of 15 requests/sec - upto 16 requests /sec. 1. Its called JMeter Throughput Constant Timer. JMeter Constant Throughput Timer is used as a goal-oriented element which helps to achieve the desired throughput. To implement pacing in Apache JMeter™, we can use either use Groovy Scripting or one of these two timers: the Constant Throughput Timer or the Throughput Shaping Timer. jmeter. Name: To provide the name of the timer; Comments: To provide arbitrary comments (if any); Number of Simulated Users to Group by: This attribute is used to define the number of threads to release at a time. BSF Timer. Testing without a JMeter timer can create irregular test results because the simulated requests will come in a different pattern than. Target throughput (in samples per minute) value lets you manage the frequency for your requests. I also had constant. There are two different ways of pacing the requests: - delay each thread according to when it last ran - delay each thread. 1. added a constant throughput timer to the ultimate thread group and gave the value as 480 requests per minute. The test plan currently uses two thread groups and runs those in loops. The ability of the server in terms of how much load it can take. Skip to content Toggle navigation. It may decrease if other timers deny the constant. according to your application design you can retry this. For further detail check JMeter blog about Constant Throughput Timer. Timer in JMeter is easy but crucial part of JMeter where we have to manage the thread user count and time to apply the load to the application. 0); Throughput Shaping Timer (can be installed via JMeter Plugins Manager); All above can pause JMeter threads in order to limit the throughput (requests per unit of. The Throughput Shaping Timer plugin adds the following features to JMeter: The Throughput Shaping Timer element - a timer that sets the desired RPS schedule via the JMeter GUI. If your workload patterns are more complex consider using Throughput Shaping Timer在 JMeter中定时器 用来设置延时和同步，以调节请求的发送速率，那么如何产生固定 吞吐量 的压力哪？. asked Mar 4, 2021 at 6:07. 1 Answer. So you creating the excessive number of threads and then the timer will. Oct 10, 2022 at. Jmeter measures throughput by observing the. HTTP is a stateful protocol, it means that JMeter's HTTP Request samplers wait for response prior to sending a new request so. Results Action Set Handler 4. Uniform Random Timer. The formula is: Throughput = (number of requests) / (total time). To get the exact sampler's count at the end of the test, you need to eliminate transaction's count from the aggregate report to check whether constant throughput timer is working fine or not. Remember - if the application itself is not supporting the desired throughput, jmeter can not help here. If our server is not able. It will also give you the saturation point and the bottleneck in case. Listeners, may be placed directly under the test plan, in which case they will apply to all the thread groups. The most intuitive thing I could think of was using Constant Throughput Timer to control the number of requests sent,. I can think of 2 reasons: Given 8 Thread Groups with 5 virtual users you're accessing your application with 40 concurrent users and it might be the case the application gets overloaded hence response time increases as concurrency increases. Constant Throughput Timer added with throughtput = 10 and Calculate Throughput based on = all active threads. org. July 1, 2023 by PerfMatrix. This component introduces pauses to the test plan in such a way as to keep the throughput as close as possible to the target value specified. Tell JMeter to parse the HTML file and send HTTP/HTTPS requests for all images, Java applets, JavaScript files, CSSs, etc. Constant Timer; Gaussian Random Timer; Uniform Random Timer; Constant Throughput Timer; Synchronizing Timer; JSR223. The purpose of the ‘Timer’ element is to pause a JMeter Thread for a certain amount of time. Total no of transactions = 40 (100 requests) Duration = 5m i. You can see that Start time difference between 1st request and 41st request is 1 minute. The main idea is increasing the load gradually so you won't kick off all 84 users at once but rather start with 1, after certain time add another one, etc. Gaussian Random Timer. Constant Timer. 1. If you need to execute 1000 requests in 60 minutes you need to run 16. In JMeter, there are 9 different Timer types. One of the most commonly used timers in JMeter, the Constant Throughput Timer enables you to decide how many samples should be executed per minute. For each thread, the variable will be assigned one of the values from the series in sequence. I do not want to "pre-decide" what throughput I want. First of all ensure that you're following JMeter Best Practices as it might be the case JMeter configuration is not suitable for kicking off that many threads. This timer tries to maintain a constant throughput throughout the test and achieve the target. Of course the throughput will be lower if the server is not capable of handling it, or if other timers or time-consuming test elements prevent it. Its called JMeter Throughput Constant Timer. Uniform Random Timer. If you want to limit JMeter's throughput to 1100 requests per minute consider using Constant. The Constant Throughput Timer. GitHub Repo: It has mentioned that constant throughput variable value can be changed using a JavaScript or BeanShell function to provide a changing value. apache. You can use Constant Throughput Timer or Throughput Shaping Timer in order to limit JMeter's throughput to the given numbers and see whether it will be able to complete 10k requests in 1 hour or not. Despite its name Constant Throughput Timer doesn't have to be "constant", you can define throughput default value using __P(). if the transaction controller has 3 child samplers and you want the whole transaction to be executed 100 times/minute - you need to set the target throughput to 300 requests/minute. JMeter also provides a timer component, ‘Constant Throughput Timer’, which you can use to set the value of Transactions per. Constant Throughput Timer can only pause threads in order to limit JMeter's throughput to the defined value. If you change the Constant Timer is zero, you will see the result is changed. you will be able to send 50 requests per second, etc. Do not include multiple CTT in your test script as it will lead to a hoax. jmeter. And if you changed load generator machine or server. My load would be held for 3 minutes. correct use of throughput controller (JMeter) Main thread is set to 50 concurrent users (looping - as testduration will be scheduled). I ran it for 10 mins. Có rất nhiều timers được cung cấp trong JMeter: Constant Timer, Gaussian Random Timer, Uniform Random Timer, Synchronizing Timer, etc. Constant Throughput Timer treats samplers individually therefore you need to multiply the throughput for the transaction by the number of its children samplers, i. Test Case 2: - 6 requests per minute - 1 request each 10 seconds. View Results Tree 5. Follow. If you want to send specific amount of requests during this hour consider using Constant Throughput Timer, but be aware of the following:. Introduction to JMeter Throughput. 3. You can go for Constant Throughput Timer, despite the word "constant" in its name it doesn't have to be constant, you can use __P() function for specifying the desired throughput and amend it from Beanshell Server,. Nested Class Summary. Constant Throughput Timer cannot force threads to execute faster, it can only pause threads to limit JMeter's throughput to the defined value. JRS223 Timer. Although Constant Throughput Timer accepts value in Requests/min and you are saying that you will use 120/sec, so you will have to provide a value of 7200 in Constant Throughput Timer to achieve 120/sec. Constant Throughput Timer. can only pause the threads to limit the throughput (requests per minute) to the desired value. e. either execute this 100 times OR. Another option is implementing pacing. Constant Throughput Timer is only capable of pausing JMeter threads in order to slow them down to reach the target throughput. JMeter's Constant Throughput Timer can only pause the threads in order to limit requests execution rate to the desired value, it won't kick off extra threads if current amount is not sufficient. Target Throughput behavior of Constant Throughput Timer in JMeter. e. Long time JMeter users had to try their tests on and on, finding exact number of threads and timer delays that produce desired number of requests per second (RPS) to server. or Users - 2000. Add Constant Throughput Timer to your Test plan and configure it to send 30000 requests per minute (500 requests per second) Make sure that all the Samplers are in the Constant Throughput Timer's scope and you have. If 20 users process 2400 records per hour and each record assumes 3 web page calls, it means that 7200 requests will be made in one hour which in its turn stands for 120 requests per minute (this is what you should enter into the timer's "throughput" area) or 2 requests per second. I used 80 threads and set a Constant Throughput Timer and Variable throughput timer and i set 10 transactions per second and i when i get Jmeter logs i see max 4 transactions per second . There are 3 options to configure weighted load and highlight options provided by JMeter. JMeter Constant Throughput Timer. When you need to add a delay based on an edge condition which is not covered by other timers i. Now let us see in brief about some commonly used timers of Jmeter. JMeter Properties are global, can be accessed from different thread groups and persist all the time while JMeter is running. JMeter provides lots of ways to record the value of throughput. Lets. Ok, so I have control over the below parameters in Apache JMeter: Number of Threads (users) Ramp-up period (in seconds) How do I test for varying sampling rate and not varying user addition rate? Even a fixed sampling rate would do. JMeter Constant Timer, Constant Throughput Timer. 1. Throughout the Hold Load time(180sec) the requests will be looped. You need to run Sampler(s) at rate of 600 per minute so this is what you need to specify in the Constant Throughput Timer. How to generate number of requests per second for one user. This component introduces pauses to the test plan in such a way as to keep the throughput as close as possible to the target value specified. I have constant throughput timer which will hit 1 request in 3 minutes in my test plan due to this my requests are getting timeout as it is delaying requests to 1 hour. 10 000 requests in one hour is something like 166. Constant Throughput Timer pauses active threads to reach throughput level you define. 作用：让jmeter以指定数字的吞吐量进行压测. This is used when we want each thread to wait for the same amount of time. A Constant Throughput Timer paces the samplers under its influence so that the total number of samples per unit of. How to add a Timer-Right Click on Thread Group -> Hover over Add -> Hover Over Timer -> Click on the required Timer. If you need to use the same common steps in several Thread Groups. The timer tries to produce a constant. Total Http Requests - 24, Total Http Request/min - 12, Test Duration 2min, Waiting time between requests per minute : 60min/12req = 5sec . If you server is able to respond in constant response time then throughput will remain the same for a given number of clients (threads). JSR223 Timer. Remember 2 things: Constant Throughput Timer is precise enough on minute level, make sure your test lasts long enough so it could be. Built-in Constant Throughput Timer; Throughput Shaping Timer from jmeter-plugins. TestElement. Leave a Comment Cancel reply. can only pause the threads to limit the throughput (requests per minute) to the desired value. The. 0. Go back to the "Test Plan" node. JMeter Timers obey JMeter Scoping Rules so if you put the Constant Throughput Timer under a Thread Group - it will be applied only to this thread group. Precise Throughput Timer. If current number of threads is not enough in order to. This includes any intervals between. Constant Throughput Timer will be enough for your scenario. Each timer has a different application, which we have outlined here: Constant Timer: The most basic timer, this will simply add a delay to the threads before they are initiated. So you need to supply the sufficient amount of threads in the Thread Group. Constant Throughput Timer is only capable of pausing JMeter threads in order to limit the number of requests per second to the given value. 0. In case you have only 1 request as in your scenario then it will generate Throughput of 20 request/sec (sometimes 20. Now, add the Constant Throughput Timer. I would say that these timers are mutually exclusive. Try using Constant Throughput Timer. Ramp up 1 second for all. Select "Test Plan" node. The Constant Throughput Timer is again a more powerful Timer, not in the same way the previous. The JMeter docs in 3. I think it will be more accurate than looking at locust's current_rps tracker, especially at low load. Save my name, email, and website in this browser for the next. Constant Throughput Timer. JMeter User Defined Variable for enabling Test Duration. 2. 7 requests per second. Also Constant Throughput Timer works on minute level and your desired throughput should be. You can have one HTTP header manager at Thread level or none (as per request type). e. The achieved target may be slightly high. The following is the list of JMeter 4. As a practical example, assume you have a long-running JMeter test running in CLI mode, and you want to vary the throughput at various times during the test. Constant Throughput Timer The constant throughput timer is a special type of timer used to create pauses. Also Constant Throughput Timer is only capable of slowing down JMeter to limit its. Based on RPS you want you can either set the value low for less number of requests and more for more RPS. JMeter Constant Throughput Timer Example. In planning our load tests, our goal is often to measure whether or not our application (not just the. The Apache JMeter site actually puts the workings of the ramp-up period best:. On top of that, it tries to maintain the exact amount of arrivals for a given timeframe ( throughputPeriod ). Constant Throughput Timer treats samplers individually therefore you need to multiply the throughput for the transaction by the number of its children samplers, i. Poisson Random Timer. In case of throughput; the higher the better. If it is added at the Test Plan level then it acts as a global timer and the delay is added for all the samplers before the process. 2. Constant Throughput Timer; JSR223 Timer #20. you have 2 users and 2 seconds response time - the load will be 1 requests per second; you have 4 users and 2 seconds response time - the load will be 2 requests per second; etc. HTTP Sampler for GET call is used. All of the "Timer" group of elements affect the script. Simple Controller i. Its called JMeter Throughput Constant Timer. Constant Throughput Timer with a target throughput of 12000. Each JMeter thread executes samplers as fast as it can, however next iteration won't start until previous is finished so given you use 1 thread - the throughput won't be higher than application. If you need to produce the load exactly 50 requests per minute - I would suggest going for Constant Throughput Timer which can pause the JMeter Threads in order to reach the target throughput. Precise Throughput Timer (PTT) # Como mencionamos previamente, el Precise Throughput Timer (PTT) y Constant Throughput Timer (CTT) tienen como propósito regular el arribo de hilos (Vusers). Constant Timer) as a child of the 2nd request. Also, it works only on a minute level so you need to properly calculate the ramp-up period and let your test run long enough. If you want to execute 300 000 queries in 24 hours you need to introduce a rate limiting on JMeter side to execute 208. Precise Throughput Timer. "Time cap" is not a term used in the JMeter docs, but assuming what you mean, it can be set between loops by using Test Action or other JMeter mechanisms if. Implementing Pacing with Groovy Scripting. Throughput Controller - You can set the Max number of executions, OR the Percentage of executions of the sample (i. As I keep on increasing the target throughput of JMeter at runtime, I noted that the actual achieved throughput value is limited by mainly 2 factors -. Assuming there is only one request (sampler) in your Thread group and you are using the setting "All Active Threads" in Constant Throughput Timer. jmx: JMeter project file. The constant throughput timer delays the request to ensure that JMeter does not perform more requests than. It in a way reflects the capacity of the server. Add a Test Action Sampler In the "Duration (milliseconds)" field, set the value as simply $ {mydelay} Right Click Test Action Sampler > Add > Timer > Beanshell timer. A Constant Throughput Timer paces the samplers under its influence so that the total number of samples per unit of time approaches a given constant as much as possible. This timer tries to maintain a constant throughput throughout the test and achieve the target. Using JMeter, the constant throughput timer is particularly useful for this. Lets consider below load scenario for example: Total no of users = 5. I have a requirement that in ultimate thread group , constant throughput value needs to be changed for every 5 mins using beanshell pre-processor. 5. If we were to add a Constant Timer to the test and set the delay to be 2000 milliseconds. This video features #Constant #Throughput Timer in #JMeter. Sorted by: 0. Precise Throughput Timer → this timer will vary its delay interval to keep requests at or below a certain threshold. The Constant Timer can be used to pause each thread for the same “think time” between requests. if you set it to 1, the thread will only send one request per minute). It can be defined in terms of a variable or function call, and the value can be changed during a test. I also changed the heap variable to this and i have a virtual machine with 32. Test Plan 2. Thanks @Dmitri. If you're using > 1 virtual user and uncertain regarding ramp-up settings consider using Throughput Shaping Timer which is more precise out of the box. Select it and you will see 3 fields as below. Share. I have tried JMeter with a constant throughput timer with throughput = 1500000 per second and running 1000 threads. I use JMeter for web testing. In particular the most commonly used elemends are: Synchronizing Timer – to pause threads unless certain number will be reached and fire them all at the same time. And one of them has an obvious title – “Constant Throughput”. java by adding it to the source directory of my project folder. I have single thread group with 40 users. Jmeter variable value update based on time. This time you will be able to correlate increasing load with other metrics like response time, throughput, number of errors, etc. Example: If Constant Delay Offset is given 1000 and deviation is given 200 then Gaussian Random Timer will generate the random number in the range. I think you need to consider switching to Constant Throughput Timer, 100 transactions per hour == 1. 7. jmeter; performance-testing; Share. Unless you're doing spike testing you should be increasing the load gradually as if you release all the users right away you will get much less information and in case of gradual increasing the load you will be able to correlate it with increasing response time and. 1. Por ejemplo, cuando necesitamos mantener el servidor bajo cierta presión durante mucho tiempo, podemos controlar el rendimiento a través de este temporizador. Despite its name Constant Throughput Timer doesn't need to be "constant", you can define the desired throughput via JMeter Property using __P() function like ${__P(throughput,)} and amend the property value using i. Let’s think about an end-to-end scenario for an e-commerce website. As you see, no other timers except Througput shaping timer. if the transaction controller has 3 child samplers and you want the whole transaction to be executed 100 times/minute - you need to set the target throughput to 300 requests/minute. How to create JMeter test with parallel execution in one thread group with specific throughput? 0. Constant Throughput Timer is available out of the box with JMeter. JMeter - Timer - "Constant Throughput Timer" C onstant Throughput Timer is used as a goal-oriented element which helps to achieve the desired throughput (Total Number of Requests). Use Precise Throughput Timer. I would say that these timers are mutually exclusive. Constant Throughput Timer is only capable of pausing JMeter threads in order to limit the number of requests per second to the given value. In actual execution, in 1 hour. Constant Throughput Timer acts precise enough on minute level so expect your number of requests applied from 2nd minute and onwards. The following BeanShell commands could be used to change the test:If you need provide constant load at 300 requests per second rate - you'll need Constant Throughput Timer. While running test simulations, it is sometimes necessary to be able to specify the throughput in terms of the number of requests per minute. some examples are Constant Timer, Constant Throughput Timer. 8,610 13 13 gold badges 104 104 silver badges 233 233 bronze badges. Just to recall in terms of Apache JMeter the meaning of Throughput is ‘requests per second’ or ‘samples per second’ send to the server by JMeter. Adding extra node will add extra 200 TMP. Hot Network QuestionsYou can slow down JMeter's number of requests per minute by using Constant Throughput Timer. You could make the target throughput a variable too. Now, add the Constant Throughput Timer. If you get response times comparable to what you see in Fiddler. 0 (inclusive) and 1. So in total you will have approximately 50 + 5 samplers, the actual amount will vary depending on your response time. Recording scripts is where you will spend most of your time. One widget at a time is passed through a machine that stamps it with a label. Built into JMeter, there are 9 different types of timers available: . See How to use JMeter's Constant Throughput Timer article for more details. The constant timer is the basic timer among all the given ones. The value can be changed in various ways: You could set the throughput using a property or variable. A user logs in, goes to the main page, searches for a product, sees the results and goes to the detail page of one option. This ultimate thread group will give you more control over Threads. Synchronizing Timer: mình đã nói ở bài viết Nhiều user thực hiện một hành động đồng thời trên jmeter; Constant Throughput Timer: có vẻ giống với Synchronizing Timer, mình chưa dùng bao giờ. You can try setting the number of threads to i. Why even making use of the Constant Throughput Timer I sometimes get a number of requests higher than the value specify in the Target Throughput (21 in the above image) If a indicate a value of 21 in. 2. The number of requests per second has to be controlled by using constant throughput timer (or the one from jmeter-plugins). If it is added at the Test Plan level then it acts as a global timer and the delay is added for all the samplers before the process. thread group (thread = 1000, ramp up = 100 sec, loop count = 1) loop controller( above 3 request with loop count = 12) constant timer = 300000 millisecond. Placing the HTTP sampler under different threads is to send the API requests in parallel, because JMeter by default will run threads simultaneously when “Run Thread Groups consecutively” under the test plan is unchecked. The name that we have given is displayed on the tree and here. It pauses the execution of test for a specified constant amount of time. 2. Constant Throughput Timer - You can set the amount of Throughput (samples per minute) by adding a timer after the request to slowdown the script, so it fits the throughput value. For example, this can be used to assign a distinct user id to be used by each thread. Closed asfimport opened this issue Apr 25, 2014 · 5 comments Closed Constant Throughput Timer: Java 8 incompatibility #3368. 4K views 2 years ago Learn Apache JMeter Series. Improve this answer.

Synchronizing Timer: mình đã nói ở bài viết Nhiều user thực hiện một hành động đồng thời trên jmeter; Constant Throughput Timer: có vẻ giống với Synchronizing Timer, mình chưa dùng bao giờ. Different Thread Groups having different number of threads; Throughput Controller; Switch Controller or Weighted Switch Controller plugins. variable variable. So overall 20 users - ramped up in 1 seconds. Sorted by: 2. Given you have Loop Count set to 1 JMeter will shut down. This will ensure that request is made minimum 100 per minute. old_throughput – default intensity value, op/min. Now check the time difference between the 1st sample and 11th sample, it is 1 minute. Doing the math, it should send a request every 5 milliseconds, and being 200 Threads, it should send 200 requests/second (200*5 = 1000ms). I am developing a JMeter Script according to the below requirement. If your application can only serve 1000 requests per minute - you will have 1000 requests per minute no matter how many threads you have in the Thread Group or how many requests per minute you specify in the Constant Throughput Timer. nathan88wise (): When I specify 0 for the "Target throughput (in sample per minute)" of a Constant Throughput Timer, use either shared algorithm - "all active threads (shared)" or "all active threads in current thread group (shared)" and have a Thread Lifetime specified - the Thread Group will run with <"Number of Threads" - 1> threads. In my test plan I'm using a ThreadGroup with 5 threads, a HTTPRequest Sampler and a Constant Throughput timer with target set as - ${__P(throughput, 100)} for all active threads in current threadgroup. Constant Timer: To delay every user request for the same amount of time use Constant Timer. Nested Class Summary. e. Though the name implies it is constant, various factors affect the behavior, such as server capacity, other timers or time-consuming elements in the test. JMeter Constant Throughput Timer. 0. JMeter threads model assumes waiting for the response prior to sending the next request, if your application won't be able to handle more than 30 requests per second there is no way to get 40 requests per second using HTTP Request samplers. apache. Constant Timer. Let’s think about an end-to-end scenario for an e-commerce website. The Uniform Random Timer pauses the thread by a factor of: The next pseudorandom uniformly-distributed value in range between 0. JMeter timers mainly include Constant Timer, Uniform Random Timer, Precise Throughput Timer, Constant Throughput Timer, Gaussian Random Timer, JSR223 Timer, Poisson Random Timer, Synchronizing. In planning our load tests, our goal is often to measure whether or not our application (not just the. 2. Khi đó bạn sẽ cần sự trợ giúp từ hàm _Ramdom của JMeter. Constant Throughput Timer – introduces variable pauses, calculated to keep the total throughput as close as possible to a given figure. so in your plan, you add. Apache JMeter is an open source Java based tool that enables you to perform functional, load, performance and regression tests on an application. Adding a constant timer on a transaction. N. The first request wil receive the correct amount of throuhput the first time, and so will the 2nd request. Jmeter Throughput Shaping Timer sending more requests then desired. With regards to point 1 be aware that Constant Throughput Timer can only pause threads in order to limit JMeter's throughput to the desired number of requests per minute. Long time JMeter users had to try their tests on and on, finding exact number of threads and timer delays that produce desired number of requests per second (RPS) to server. However, a couple of advantages are the request bursts are more consistent in nature, and the samples lie very close to the median value, as can. Changing this consistent worth during the test is additionally. getMaxThroughputAsInt(ThroughputController. Target throughput (in minutes): 3000. 3. Basic Timers: Constant Timer → the most basic timer type which adds a simple delay to your test with no other parameters. Sorted by: 2. Constant Throughput Timer is only capable of pausing JMeter threads in order to slow them down to reach the target throughput. In Validate Thread group I have accessed property by function ${__P(some-property-name,)}, included a constant throughput timer with values of 73/min and have also set a throughput controller with. Constant Throughput is a calculator that checks the number of requests per time unit. I am developing a JMeter Script according to the below requirement. Different Timer Types. 0. Constant Timer at Thread Group level. So the real throughput depends on 2. Constant Throughput Timer Value=120/sec is used. Mouse hovers "Add". The test run may be shorter as if. Constant Throughput Timer allows us to keep total throughput constant. Add a relevant JMeter Timer (i. Throughput - the Throughput is measured in requests per second/minute/hour. First of all, Constant Throughput Timer can only pause JMeter threads in order to limit JMeter's throughput to the desired value. Share. If current number of threads is not enough in order to. The total number of threads in the Ultimate Thread Group will be 250. Other elements, e. Throughput Shaping Timer. Add Synchronizing Timer to the request and set Number of Simultaneous Users to Group by to X. However it is precise enough only on "minute" level so you might need to play with ramp-up period. Initial delay=0 Startup Time=250 Hold Load= 400 seconds Shutdown time= 250. In JMeter you can control the connect/response timeouts at the "Advanced" tab of the HTTP Request sampler (or even better HTTP Request Defaults) where you can increase the default timeouts to the desired values:. 2. JRS223 Timer. Given your setup the only way of having exactly 399600 samplers is using Throughput Controller in. HTTP Cache Manager must be included in your test plan if you have enabled your HTTP sampler to “Retrieve All Embedded Resources”. The time is calculated from the start of the first sample to the end of the last sample. JMeter has a group of elements, which are called “Timers”. Like this: Throughput Controller config: Based on is Percent Execution and Throughput is 20. This includes any intervals between samples, as it is supposed to represent the load on the server. 0. First of all try increasing the number of threads.
