Tổng kết 2 Answers. On top of that, it tries to maintain the exact amount of arrivals for a given timeframe ( throughputPeriod ). Test Case 1: - 3 requests per minute - 1 request each 20 seconds. This is "closed workload" approach, and it has major drawbacks (see here why). This implies per minute 10 requests will be executed. Very silly mistake with a conclusion: Check your throughput value, test for longer periods. HTTP Sampler ii. 4. If you want to slow. JMeter configuration and start from the command line. Since: 4. If you set its value as “1. 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. The main factor is your application response time, if it will be 1 second - go for 400 threads for 1 request, if it is 2 seconds - you will need 800 threads for 1 request, etc. Recording scripts is where you will spend most of your time. JMeter Constant Timer, Constant Throughput Timer. This capability is really helpful for debugging tests in real time. Constant Throughput Timer. This would allow you to adjust it via Command Line in real time, as the test script is being executed. The constant timer is the basic timer among all the given ones. Constant Throughput Timer The constant throughput timer is a special type of timer used to create pauses. 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. 2. 1 Answer. In this case, we are using a JMeter plugin – Throughput Shaping timer. I'm thinking that in my overall Test Plan, I will add all the a). 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. I am using a Constant Throughput Timer with "Calculate throughput based on: all active threads in current thread group" selected. The purpose of the ‘Timer’ element is to pause a JMeter Thread for a certain amount of time. Constant Delay Offset (in milliseconds): The number shows a constant delay which will be added in random number generated by Gaussian Function in the range of given deviation value. For example, this can be used to assign a distinct user id to be used by each thread. Based on RPS you want you can either set the value low for less number of requests and more for more RPS. The test plan currently uses two thread groups and runs those in loops. We highly recommend using the Uniform Random Timer. JMeter User Defined Variable for enabling Test Duration. Constant Throughput Timer is precise enough at minute level, so if you configure your test to last longer - you will see the throughput going down gradually and after 1st minute it should be throttled to your 100 requests per minute. And then execute the test we see that the execution of each sampler is delayed by 2000 milliseconds. Constant Throughput Timer pauses active threads to reach throughput level you define. Figure shows, Constant Throughput Timer for 60 requests per. Uniform Random Timer. Results Action Set Handler 4. See Also: Serialized Form. The number of requests per second has to be controlled by using constant throughput timer (or the one from jmeter-plugins). 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. 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. First of all try increasing the number of threads. Constant Throughput Timer will let you control the flow of. Except for /pdfbill (set to 50%), as we only want 25 concurrent users here instead of 50 users. If your goal is to execute X requests per second - go for one of the following test elements: Constant Throughput Timer; Precise Throughput Timer (available since JMeter 4. The main goal of. JMeter offers several options to control the load. We will conduct a sample load test with 100 concurrent users (threads) and evaluate the throughput value. I am developing a JMeter Script according to the below requirement. 1. See How to use JMeter's Throughput Constant Timer guide for more details. Components presented here provide the functionality to introduce User Think Time in various forms among samplers. I ended up using constant_throughput to control the number of requests per second. But if I place my requests in separate Thread Groups - Throughput Controller doesn't work. It exposes the following component properties that contain information about the duration and current state of the test where elementName will be the name of your timer. JMeter BeanShell Timer is a scripting-based timer. piotr. Constant Throughput Timer is only capable of pausing JMeter threads in order to slow them down to reach the target throughput. Changing this consistent worth during the test is additionally. 4. I think you need to consider switching to Constant Throughput Timer, 100 transactions per hour == 1. Using a uniform random timer allows you to pause the test execution for a random time, where you can. See How to use JMeter's Constant Throughput Timer. correct use of throughput controller (JMeter) Main thread is set to 50 concurrent users (looping - as testduration will be scheduled). Constant Throughput Timer: Target - 60,000/min (60 secs) - all active threads, Threads (Users) - 200 with Ramp up - 1 sec, Duration: 1 hour. old_throughput – default intensity value, op/min. So you must supply enough threads in the Thread Group to create more requests per second than you're trying to achieve and then limit the number of requests per second to the desired rate using. e. Constant Throughput Timer is only capable of pausing JMeter threads in order to limit the number of requests per second to the given value. Config Elements, b) a Thread Group (probably Ultimate), c) a Constant Throughput Timer (to limit the overall transaction rate), then d) 8 ThroughPut Controllers, and then INCLUDE the scripts in respective controllers, e) Listeners. Precise Throughput Timer → this timer will vary its delay interval to keep requests at or below a certain threshold. This time you will be able to correlate increasing load with other metrics like response time, throughput, number of errors, etc. Throughput controllers for all API calls is set to 100% 'Percent Executions' with 'Per User' ticked off. Open your JMeter script and right click on Thread Group. If the machine stamps sixty widgets in one minute, it’s throughput is one widget per second. Constant Timer or Gaussian Random Timer or Uniform Random Timer or whatever. Boundary value Extractor iv. That means 40 samples has been executed in 1 minute. Throughput Controller - You can set the Max number of executions, OR the Percentage of executions of the sample (i. Test Plan. Ramp-up is the time for JMeter to kick off the virtual users from point 1. 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. Throughput Shaping Timer is a plugin and you need to install the plugin. 0. 2. Constant Throughput Timer: Java 8 incompatibility #3368. JSR223 Timer. Constant Timer. Subscribe. See Also: Serialized Form. We should see. What are Samples in JMeter? It generates one or more sample results. 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. 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？可以使用常数吞吐量定时器(Constant Throughput Timer)来实现。 下面举例来看看如何做到以固定吞吐量发送请求，创建…Tool ที่เราใช้ในการทำ performance test ก็คือ JMeter ซึ่งเป็น tool opensource ที่เขียนด้วย Java. Select "Test Plan" node. 0 (inclusive) and 1. 3. Do not select "This thread only" value for Timer added at root, as it will change the result. With 100 threads you will get 50 requests per second. 1. The application. e. Allocate the target throughput to required number (30 in this case). Adding a constant timer on a transaction. 0. java:131. This timer generates Poisson arrivals with constant throughput. Constant Throughput Timer. I have used "jp@gc - Throughput Shaping Timer" But unable to achieve expected TPS. 2. July 1, 2023 by PerfMatrix. Add Synchronizing Timer to the request and set Number of Simultaneous Users to Group by to X. Now, add the Constant Throughput Timer. Thread group elements are the beginning points of any test plan. To add a timer element, we need to right-click on the Thread Group element and select Add, Timer, Constant Timer. I am trying to configure a test for signup-login with invalid credentials imitating bruttforce attack. Constant Throughput Timer treats samplers individually therefore you need to multiply the throughput for the transaction by the number of its children samplers, i. 0. So you must supply enough threads in the Thread Group to create more requests per second than you're trying to achieve and then limit the number of requests per second to the desired rate using Constant Throughput Timer. You may need to try it out in a few runs to find the optimum value of sleep time to get the desired throughput. Sample Time of Sample 2 is 172 ms. Despite its name Constant Throughput Timer doesn't have to be "constant", you can define throughput default value using __P(). log can be very useful for troubleshooting JMeter-specific issues. 1. This timer generates Poisson arrivals with constant throughput. And run the following to. Another option is implementing pacing. 8K subscribers. 作用：用来设置集合点，其作用是：阻塞线程，直到指定的线程数量到达后，再一起释放，可以瞬间产生很大的压力. at org. Like this: Throughput Controller config: Based on is Percent Execution and Throughput is 20. 0. jmeter里面不可以直接控制吞吐量，但是我们可以通过操作并发数变相改变吞吐量。. JSR223 Timer. In some cases, the Timer is used to implement the Pacing. If it is. It will introduce the random relays between requests in such a way that required throu. Request Oriented Goal: In such types of goals, we need to achieve the defined number of requests in an hour. org. The time unit is chosen so that the displayed rate is at least 1. No other timer or plugin is added in the test plan. 让线程暂停一个随机时间。由两部分组成： Random Delay Maximum 随机延迟部分; Constant Delay Offset 固定延迟部分; 实例： 1、添加线程组，添加 Uniform Random Timer ，添加HTTP请求，设置固定延迟部分未2000毫秒，随机延迟部分在2000ms。也就是线程延迟在2-4s之间Built-in Constant Throughput Timer; Throughput Shaping Timer from jmeter-plugins. e. B. However it is precise enough only on "minute" level so you might need to play with ramp-up period. Improve this question. Constant Throughput Timer added with throughtput = 10 and Calculate Throughput based on = all active threads. Actually you can just provide enough users and focus on controlling how often they will be sending requests via Constant Throughput Timer or Throughput Shaping Timer. 6 transactions per minute. 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. Thread Group 3. 3. " --- this is not entirely true. HTTP Sampler for GET call is used. In JMeter, there are 9 different Timer types. Constant Throughput Timer Controlando el número de solicitudes por minuto (es decir, la forma de controlar el rendimiento) para controlar si se debe retrasar la pausa. Throughput increased by factor of 2. （1）Number of Simulated Users to Group by：模拟用户的数量，即指定同时释放的线程数数量，若设置为0，等于设置. So in total you will have approximately 50 + 5 samplers, the actual amount will vary depending on your response time. 一定のタイマーは、一定の遅延時間の値を追加することで構成できる一定の時間だけ次の要求を. This can be used to add some delay/think time between each request. (2) Throughput Controllers to distribute the load in Percent [20% and 80% of total 24. It in a way reflects the capacity of the server. Click Add –> Timer –> Constant Timer. Constant Timer or Gaussian Random Timer or Uniform Random Timer or whatever. It may decrease if other timers deny the constant. 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. Precise Throughput Timer is more "precise" but a little bit harder to use as you need to provide controlled throughput. if you set it to 1, the thread will only send one request per minute). JMeter has a group of elements, which are called “Timers”. Though you can develop test plans manually by building them from within the JMeter GUI, or generating them via some domain-specific language (DSL), recording scripts by JMeter's HTTP(S) Test Script Recorder is one of the. Skip to content Toggle navigation. One widget at a time is passed through a machine that stamps it with a label. In order to be able to send 400 RPS with 400 threads your application must respond in 1 second or less because JMeter waits for the response from previous sampler before starting the next one. Constant Throughput Timer is available out of the box with JMeter. ramp up to 6000 samples per min and so on up to. Concurrency Thread Group doesn’t provide the ability to define initial delay, step transition and ramp-down - which the Stepping Thread Group does. Use Cases. Throughput timer is in root of test plan, Where as other timers are only applicable within scope of controllers. JMeter also provides a timer component, ‘Constant Throughput Timer’, which you can use to set the value of Transactions per. 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. variable variable. If you're not able to reach the target throughput the reasons could be in: There are not enough threads in the Thread Group to conduct the desired throughput. “Calculate throughput “ option can be varied based on the current thread, all threads in your test plan. "Throughput depends on response time. The Constant Throughput Timer. 1. This includes any intervals between samples, as it is supposed to represent the load on the server. 10 000 requests in one hour is something like 166. Gaussian Random Timer. Below timers are used to implement pacing in Jmeter to achieve the desired load/Business transactions. 4. 让线程暂停一个随机时间。由两部分组成： Random Delay Maximum 随机延迟部分; Constant Delay Offset 固定延迟部分; 实例： 1、添加线程组，添加 Uniform Random Timer ，添加HTTP请求，设置固定延迟部分未2000毫秒，随机延迟部分在2000ms。也就是线程延迟在2-4s之间For example, if you need 100 RPS, then “Target Throughput” value should be 6000/min in Constant Throughput Timer. Throughput Controller - You can set the Max number of executions, OR the Percentage of executions of the sample (i. I have implemented a different solution, inspired by Jmeter's constant throughput timer. Leave a Comment Cancel reply. Its called JMeter Throughput Constant Timer. As per JMeter Glossary: Throughput is calculated as requests/unit of time. Jmeter variable value update based on time. 4 requests per minute. jmeter. 1) with Constant Throughput Timer value as 1200/min with "All active threads" and Timer added at the root of script.

Figure 01: JMeter Timer Elements Scope of JMeter Timer: 1. This includes any intervals between. The time is calculated from the start of the first sample to the end of the last sample. e 300s. As per documentation>. Save my name, email, and website in this browser for the next. Target throughput (in minutes): 3000. This will add Constant Timer at Thread Group level. You can try setting the number of threads to i. 下面举例来看看如何做到以固定 吞吐量 发送请求，创建一个 JMeter 脚本，加入了若干. This way, You can use constant throughput timer in your load test plan to achieve. JMeter Timers obey JMeter Scoping Rules so it's sufficient to add a single Timer and it will apply the desired throughput to all Samplers it its scope. 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. 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. Example configuration: Add Constant Throughput Timer as a child of the Login sampler. I think the documentation was before Ultimate Thread Group was introduced. Testing without a JMeter timer can create irregular test results because the simulated requests will come in a different pattern than. Now check the time difference between the 1st sample and 11th sample, it is 1 minute. 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. e. That means 40 samples has been executed in 1 minute. 4 requests per minute, it can be done using i. 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. Constant Throughput Timer config: Target Throughput is 600. Different Timer Types. apache. 6. Jmeter: Constant throughput Timer with Ultimate Thread Group. Introduction. 1 Answer. It can be defined in terms of a variable or function call, and the value can be changed during a test. JMeter provides lots of ways to record the value of throughput. Because JMeter sometimes displays throughput in per minute and sometimes in per second, whereas the hits per second is always per second. 1. Throughput Controller. I have a JMeter Test Plan where I am using different Timers like Throughput Timer, Constant Timer & Synchronizing Timer. 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. JMeterは一般的にWebシステムに一定のアクセス負荷をかける試験ツールです。 通常機能ではアクセス負荷量の上げ下げが困難ですが、外部ライブラリ(Throughput Shaping Timer)を組み込むことでグラフィカルかつ簡単に実現できたので紹. jmx: JMeter project file. The constant timer pauses the test execution for a constant period. Constant Timer at Thread Group level. Introduction to JMeter Throughput. 0. Timers provided in JMeter Constant Timer. First of all, Constant Throughput Timer can only pause JMeter threads in order to limit JMeter's throughput to the desired value. Throughput Shaping Timer. 1 Answer. Looking into the Average Response Time which can be as high as > 1. Then extract the file and run JMeter: $ tar -xf apache-jmeter-5. 1 Answer. You can see that Start time difference between 1st request and 41st request is 1 minute. Constant Throughput Timer can only pause threads in order to limit JMeter's throughput to the defined value. Basic Timers: Constant Timer → the most basic timer type which adds a simple delay to your test with no other parameters. Given you have the timer you produce less load so application has more chance to respond properly. A good position would be a direct child of the Thread Group. Instead of focusing on trying to hit the same request at the same time, which is fiddly in JMeter, you should setup your test to be a realistic representation of the sort of load you want your application to support. To achieve this I have configured a Constant Throughput Timer to 12000 requests per minute (active for. So the scenario is the next: Attempt to log in with invalid params in a loop. So you need to supply the sufficient amount. Constant Throughput Timer introduces variable pauses, calculated to keep the total throughput (in terms of samples per. You can consider switching to Concurrency Thread Group and Throughput Shaping Timer. so I used a ultimate thread group and set the threads to 200 and ramp up was 200seconds. Thanks @Dmitri. Share. 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. To see the full JMeter Timer List, click on the Thread Group -> Add -> Timer. Constant Timer) as a child of the 2nd request. JMeter also provides a timer component, ‘Constant Throughput Timer’, which you can use to set the value of Transactions per. Alternative options are: JMeter also provides a useful timer component to configure or set a constant throughput value to test the application load. 1. 5. If you introduce artificial delay of 3 seconds - it will make the overall throughput lower. 1000 and slowing the requests down using Constant Throughput TimerI've set up a jmeter distributed testing setup with one master and multiple slaves. First of all, Constant Throughput Timer can only pause JMeter threads in order to limit JMeter's throughput to the desired value. Dmitri T. As I can see, Constant Throughput Timer ensures requests completion rate (for example, if I specify "2" in the timer, it will slow down the thread so that 2 requests are finished per minute) My test plan with Constant Throughput Timer. BSF Timer. It is important to get this peak throughput level correct because otherwise you either end up with a load that is too high (you waste time solving problems that are not problems) or too low (you don't find problems that are real problems) but if you already have. This video features #Constant #Throughput Timer in #JMeter. Plus “Constant Delay Offset”. You can add this element to your test plan by following “Thread Group -> (right click) -> Add -> Timer -> Constant Throughput Timer” path. jmeter. 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. Throughput Shaping Timer. Follow edited Mar 4, 2021 at 7:35. Follow answered Nov 2, 2022 at 4:51. 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. 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. thread numbers, target throughput and what kind of information needs. The easiest way of controlling the number of requests per second (throughput) in JMeter test is using Constant Throughput Timer. This timer tries to maintain a constant throughput throughout the test and achieve the target. Remember - if the application itself is not supporting the desired throughput, jmeter can not help here. All of the "Timer" group of elements affect the script. 0. 6. You cannot, JMeter waits for previous Sampler response prior to executing next Sampler so if you put all the Samplers under one Thread Group all the requests will be executed at the speed of the slowest request. Below you will find a categorized list of the most common timer elements included with JMeter. TestElement. If current number of threads is not enough in order to. Hot Network QuestionsYou can slow down JMeter's number of requests per minute by using Constant Throughput Timer. Issue: If i run the test, I was expecting the min throughput of 15 requests/sec - upto 16 requests /sec. If you want to execute 300 000 queries in 24 hours you need to introduce a rate limiting on JMeter side to execute 208. 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). Constant Timer: To delay every user request for the same amount of time use Constant Timer. I think it will be more accurate than looking at locust's current_rps tracker, especially at low load. 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. Constant Throughput Timer can only pause the requests to limit JMeter samplers execution rate to desired value, it won't kick off any extra threads if the current throughput is lower than expected. You can have one HTTP header manager at Thread level or none (as per request type). The Constant Timer is self-explanatory: it delays each sampler by a constant Thread Delay value. This ultimate thread group will give you more control over Threads. Based on RPS you want you can either set the value low for less number of requests and more for more RPS. It is often the first step to develop test plans for applications. 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. If current number of threads is not enough in order to. Remember 2 things: Constant Throughput Timer is precise enough on minute level, make sure your test lasts long enough so it could be. How to create JMeter test with parallel execution in one thread group with specific throughput? 0. This is what we need to control request frequency. All you need to do is to slow it down a little bit, one of the options is adding a Constant Throughput Timer. 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. e. Try using Constant Throughput Timer. In planning our load tests, our goal is often to measure whether or not our application (not just the. 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. Target throughput (in samples per minute) value lets you manage the frequency for your requests. รวมถึง. Let’s think about an end-to-end scenario for an e-commerce website. Constant Timer. The thread delay is a constant in milliseconds: Uniform Random Timer: One step above the basic. 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. I ended up using a Test Action with 30s pause. 7. In the JMeter script, Constant Timer is used to add a constant delay before processing a sampler. Set Target Throughput = 40. I would say that these timers are mutually exclusive. The difference between the uniform random timer and other two random timers (Gaussian and Poisson) are: 1. Constant Throughput Timer. If your scenario is to execute 100 requests evenly distributed across one minute you should rather go. Use CTT in Test Plan level,not in thread group level. This is "closed workload" approach, and it has major drawbacks (see here why). First of all, Constant Throughput Timer can only pause JMeter threads in order to limit JMeter's throughput to the desired value. JRS223 Timer. It pauses the execution of test for a specified. Other timers may impact constant throughput timer target, so it is recommended not to use other timers. 1 Answer. Total no of transactions = 40 (100 requests) Duration = 5m i. Testing without a JMeter timer can create irregular test results because the simulated requests will come in a different pattern than. Plus “Constant Delay Offset”. This will add Constant Timer at Thread Group level. The test run may be shorter as if. JMeter: Holding Session for a certain. It will also give you the saturation point and the bottleneck in case. 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. Share. For instance 200k requests per hour is more or less 55 requests per second, if your application response time is 1 second - you will need 55. Throughout the Hold Load time(180sec) the requests will be looped. JMeter Constant Throughput Timer is used as a goal-oriented element which helps to achieve the desired throughput. Follow answered Oct 22, 2015 at 16:42. Throughput Shaping Timer. log is actually included in the bzt. So you will get 10 threads up and running only by 19th second. JMeter Constant Throughput Timer. bsh_loc – folder, containing bsh-files. Ori Marko Ori Marko. Uniform Random Timer. You can specify the pause in ‘Thread Delay’ field. 5K users or somewhere around it. Constant Timer. 2. Constant Throughput Timer. Total Http Requests - 24, Total Http Request/min - 12, Test Duration 2min, Waiting time between requests per minute : 60min/12req = 5sec . Por ejemplo, cuando necesitamos mantener el servidor bajo cierta presión durante mucho tiempo, podemos controlar el rendimiento a través de este temporizador. Sorted by: 2. If you have 10 virtual users which can be executed at rate of 10 requests per second you will not be able to reach 20 requests per second without. Now let us see in brief about some commonly used timers of Jmeter. My purpose is to to use Throughput Shaping Timer via JMeter API in my code programmatically. Ramp up 1 second for all. jmeter. Precise Throughput Timer. The timer tries to produce a constant. It seems that all the configurations were correct, but the actual number of requests in the constant throughput timer was too low. 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. Example 1: you have submitted a request and it returns "pending" status. What is throughput time in JMeter? Throughput is calculated as requests/unit of time. or Users - 2000. This timer tries to maintain a constant throughput throughout the test and achieve the target. JMeter. Open your JMeter script and right click on Thread Group. For each thread, the variable will be assigned one of the values from the series in sequence. 1.
