Here are the workarounds: Calculate the number of threads you need to achieve your. If it is added under a sampler then the parent sampler will wait for the defined time. e. Despite word "constant" in its name, you can use i. Share. added a constant throughput timer to the ultimate thread group and gave the value as 480 requests per minute. My test config in jmeter. jmeter. How do I achieve a certain TPS in Jmeter. 3. This video features #Constant #Throughput Timer in #JMeter. Adding extra node will add extra 200 TMP. Basic Timers: Constant Timer → the most basic timer type which adds a simple delay to your test with no other parameters. A constant throughput timer in JMeter is used to achieve the actual output by computing the total number of requests. I would say that these timers are mutually exclusive. Below screenshot is list of all Timers provided by JMeter to control the load. The application. JMeter slaves are totally independent beasts hence they don't know anything about each other so both nodes will produce 200 TMP therefore you will get 400 in total. I am having 5 request inside that. either execute this 100 times OR. The easiest way of controlling the number of requests per second (throughput) in JMeter test is using Constant Throughput Timer. JMeter is not capable of immediately stopping 1000 threads when the Throughput Shaping Timer reaches its duration limit, JMeter "tells" threads to stop one 1200 seconds pass and it might take a while to gracefully shut the threads down. can only pause the threads to limit the throughput (requests per minute) to the desired value. timer. Add a relevant JMeter Timer (i. Constant Timer. How to calculate. Add two entries to the "User Defined Variables. S3E3 Learn JMeter Series - Constant Throughput Timer. You can specify the pause in ‘Thread Delay’ field. It means that you have to implement the thread delay logic by yourself using one of the supported scripting languages. User variables can be referenced in any field of any JMeter Component. It seems that the Constant. Ramp-up is the time for JMeter to kick off the virtual users from point 1. I have a requirement that in ultimate thread group , constant throughput value needs to be changed for every 5 mins using beanshell pre-processor. JMeter Constant Throughput Timer is used as a goal-oriented element which helps to achieve the desired throughput (Total Number of Requests). I would suggest going for Constant Throughput Timer. 1. The total number of requests JMeter will be able to make will mostly depend on application response time. it worked. Target throughput (in samples per minute) value lets you manage the frequency for your requests. The difference between the uniform random timer and other two random timers (Gaussian and Poisson) are: 1. 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. 1000 and slowing the requests down using Constant Throughput TimerI've set up a jmeter distributed testing setup with one master and multiple slaves. We will conduct a sample load test with 100 concurrent users (threads) and evaluate the throughput value. 10 000 requests in one hour is something like 166. The number of requests per second has to be controlled by using constant throughput timer (or the one from jmeter-plugins). I'm currently using Apache JMeter to run load tests on the REST interfaces of my backend application. 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. BeanShell Timer. You can consider switching to Concurrency Thread Group and Throughput Shaping Timer. Nested Class Summary. If we were to add a Constant Timer to the test and set the delay to be 2000 milliseconds. It is often the first step to develop test plans for applications. JMeter now supports. 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. 0 and Calculate Throughput based on is all active threads. 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. 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. When I specify 50 threads on the Thread Group and a throughput of 1 sample per minute, I see 50 samples go through immediately and then 1 sample per minute after that. I have used "Constant Through Timer" to control the flow of transactions. variable variable. Constant Throughput Timer; Throughput Shaping Timer; Precise Throughput Timer; Random number of messages in the request body payload: in both tools you will have to write some code for this, in LoadRunner you basically have to write the code for everything, in JMeter you can add JSR223 PreProcessor and use Groovy. You are right that Concurrency Thread Group is missing features of Stepping. This timer tries to maintain a constant throughput throughout the test and achieve the target. 1) with Constant Throughput Timer value as 1200/min with "All active threads" and Timer added at the root of script. If you need to execute 1000 requests in 60 minutes you need to run 16. The Constant Throughput Timer will add random pauses between requests during test execution to match the required throughput figure (samples per minute). 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. I have tried with below jmeter tools. 1. You need to decrease your ramp-up time to 100 in order to be able to hit first request with 10 users. tgz (or whatever version you downloaded) Change into the unzipped directory: $ cd apache-jmeter-5. This timer generates Poisson arrivals with constant throughput. jmeter_loc – the full path to the root jmeter folder. The test plan currently uses two thread groups and runs those in loops. If the machine stamps sixty widgets in one minute, it’s throughput is one widget per second. Given here are some JMeter listeners that you can use for this purpose: Summary Report Aggregate Report Aggregate Graph Graph Results. – EBDS. e. "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. Improve this answer. If you want to slow down JMeter to the desired number of requests per minute it can be done using Timers. Constant Throughput Timer can. For different time of the day I'd use a different throughput value. Introduction. All you need to do is to slow it down a little bit, one of the options is adding a Constant Throughput Timer. And if you changed load generator machine or server. Concurrent users are a different way of looking at application traffic. As you see, no other timers except Througput shaping timer. JMeter understand Thread Group / Throughput and INCLUDE. It is not necessary to have a separate HTTP header manager with each request unless request needs a unique header. 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. Constant Throughput Timer. The Constant Timer can be used to pause each thread for the same “think time” between requests. You can specify the pause in ‘Thread Delay’ field. To elaborate - if a Constant Throughput Timer is set to 1 sample, and 1 thread is created, then the Transaction Controller is still not considered a singular sample as far as CTT is. Right click on "Test Plan" node. Throughput shaping timer or CTT to control the expected throughput. Introduction. This ultimate thread group will give you more control over Threads. This is the function of Constant Throughput Timer. So it's your job to provide sufficient number of threads in the Thread Group. Before understanding the semantics of throughput, let’s look at the concept. Test Case 2: - 6 requests per minute - 1 request each 10 seconds. See How to use JMeter's Throughput Constant Timer for details. Lets consider below load scenario for example: Total no of users = 5. Constant Throughput Timer. I ended up using a Test Action with 30s pause. The constant timer is the basic timer among all the given ones. 866 + 172 + 5000 = 22:05:07. 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. If our server is not able. Lets. So the Sample 3 should start at the time is 22:05:07. Of course, if the server is not able to handle such a load, the throughput will. 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. These timers will pause the threads and try to achieve the specified throughput value. The Constant Timer is self-explanatory: it delays each sampler by a constant Thread Delay value. 1. This will add Constant Timer at Thread Group level. 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. If you server is able to respond in constant response time then throughput will remain the same for a given number of clients (threads). I have a cloudsearch endpoint on AWS. The purpose of the ‘Timer’ element is to pause a JMeter Thread for a certain amount of time. In this case JMeter will run 1 thread for 1 second and will try to execute as many requests as it can during this time frame. That means 40 samples has been executed in 1 minute. I have a JMeter Test Plan where I am using different Timers like Throughput Timer, Constant Timer & Synchronizing Timer. Given you have the timer you produce less load so application has more chance to respond properly. JMeter Perfmon. Total Http Requests - 24, Total Http Request/min - 12, Test Duration 2min, Waiting. Constant throughput timer (Timer) jmeter; Share. 0 (inclusive) and 1. Both the scenarios you have mentioned may require thinking for a moment that there's something fishy if they both use a different unit of time. piotr. Allocate the target throughput to required number (30 in this case). Constant Throughput Timer. Use 0 for truly random delays and a positive integer for constant. apache. Throughput Shaping Timer. There is a Constant Throughput timer, which as far as I understand, is to control throughput for individual requests. While running test simulations, it is sometimes necessary to be able to specify the throughput in terms of the number of requests per minute. This is the function of Constant Throughput Timer. Share. Nested Class Summary. タイマーがない場合、JMeterは数分の1秒で次のリクエストを送信します。. Remember 2 things: Throughput Timer isn't able to create threads, it can only slow them down so make sure that you provide enough threads to reach desired target throughput July 1, 2023 by PerfMatrix. View Results Tree 5. Keep the think time to create a more realistic behaviour ( optional )It might be the case Constant Throughput Timer is not "precise" enough, given you need to limit JMeter's throughput to 15 requests/minute assuming 20 threads it's better to consider Throughput Shaping Timer which has lower granularity therefore it's being applied immediately and gives exact throughput figures comparing to the. 0 elements: Constant Timer. Before we list these, it is important to state that they are the ones that come shipped with JMeter as standard, other custom timers are available, but these are the default: Constant Timer, Gaussian Random Timer, Uniform Random Timer, Constant Throughput Timer, Precise Throughput Timer, Synchronization Timer, BeanShell. The achieved target may be slightly high. 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. 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. The JMeter Timers available are as follows: BeanShell Timer. If 0 is given then JMeter will release the same number of users which is defined in the thread group. 1. 4. Constant Throughput Timer: This timer. 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. thread group (thread = 1000, ramp up = 100 sec, loop count = 1) loop controller( above 3 request with loop count = 12) constant throughput timer = 5. First of all try increasing the number of threads. 7. Below timers are used to implement pacing in Jmeter to achieve the desired load/Business transactions. Concurrency depends on your test plan and application response time. Throughput of 300 requests per minute gives 300/60 = 5 requests per second Constant Throughput Timer works on minute level so make sure that your tests lasts longer than 1 minute; Each JMeter thread representing virtual user executes nested samplers upside down, when. Throughput value in the Constant Throughput Timer can be changed to different values by using a variable or property. In case you have only 1 request as in your scenario then it will generate Throughput of 20 request/sec (sometimes 20. This is known as Think Time and Jmeter provides different types of timers to help add the right amount of between samples: Constant Timer – will pause for the same amount of time. 66 to the "Target Throughput" input (100 requests per hour / 60 minutes in hour)Parallel Controller executes all its children at the same time by kicking off extra virtual threads, it allows JMeter to simulate network footprint for specific use cases like simulating AJAX requests. Constant Throughput Timer config: Target Throughput is 600. We know that JMeter is an open-source, free tool used to conduct load and performance testing on static and dynamic web applications. JMeter timers mainly include Constant Timer, Uniform Random Timer, Precise Throughput Timer, Constant Throughput Timer, Gaussian Random Timer, JSR223 Timer, Poisson Random Timer, Synchronizing. It may decrease if other timers deny the constant. If you introduce artificial delay of 3 seconds - it will make the overall throughput lower. Follow. If it is. This would allow you to adjust it via Command Line in real time, as the test script is being executed. 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. I also changed the heap variable to this and i have a virtual machine with 32. Using JMeter, the constant throughput timer is particularly useful for this. 1 Answer. 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. In planning our load tests, our goal is often to measure whether or not our application (not just the. Constant Throughput Timer is only capable of pausing JMeter threads in order to slow them down to reach the target throughput. 50 (you may need even more)タイマーは、JMeterが次のリクエストを送信するのを遅らせるために使用されます。. 1) with Constant Throughput Timer value as 1200/min with "All active threads" and Timer added at the root of script. 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. This video features #Constant #Throughput Timer in #JMeter. 1. Jmeter: Constant throughput Timer with Ultimate Thread Group. I am adding throughput timer but then I need to set up. 0” your. 0. The timers work as expected, I would say you're getting more or less equal throughput due to your application being overloaded and responding too slow, i. I want to measure the response time of this 100 users login which I've. I want to run this test for five or ten minutes. 7 requests per second. so I used a ultimate thread group and set the threads to 200 and ramp up was 200seconds. apache. Save my name, email, and website in this browser for the next. These sample results have various features like data size, elapsed time, etc. Ramp up 1 second for all. Constant Timer with a Thread Delay of 5 milliseconds. jmeter. If you get response times comparable to what you see in Fiddler. 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 Throughput Timer allows us to keep total throughput constant. at org. Some commonly used JMeter Timers are: Constant Timer; Uniform Random Timer; Precise Throughput Timer; Constant Throughput Timer; Gaussian Random Timer; JSR223 Timer; Poisson Random. Results Action Set Handler 4. 2. JMeter Constant Throughput Timer is used as a goal-oriented element which helps to achieve the desired throughput. If you change the Constant Timer is zero, you will see the result is changed. To apply a timer to a single sampler, add the timer as a child element of the sampler. For example, if I set Constant Throughput timer throughput to be 60 per minute,. Issue: If i run the test, I was expecting the min throughput of 15 requests/sec - upto 16 requests /sec. If above information is not enough try to elaborate your query and include i. You can add this element to your test plan by following “ Thread Group -> (right click) -> Add -> Timer -> Constant Throughput Timer ” path. The timer will be applied before the sampler is executed. Constant Throughput Timer. Remember - if the application itself is not supporting the desired throughput, jmeter can not help here. To get request running each 5 seconds set "Target Throughput" to 12 requests per minute (1 request each 5 seconds) So you will have requests firing as per your requirement: For request which needs to be executed once per 5 minutes do the same but set "Target Throughput" to 0. 0. Second I would recommend checking whether your system under test has enough headroom in terms of resources (CPU, RAM, Network, Disk, etc. First of all try increasing the number of threads. 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. Follow asked Nov 1, 2022 at 13:41. Test Case 1: - 3 requests per minute - 1 request each 20 seconds. 0 (inclusive) and 1. 5K users or somewhere around it. And then execute the test we see that the execution of each sampler is delayed by 2000 milliseconds. B. If you want to have more customization over how your pacing timer works, you can do so by using Groovy. Constant Throughput Timer can only pause the threads in order to limit JMeter to the defined 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. Sorted by: 2. Response Assertion. Add Constant Throughput Timer . 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. Constant Throughput Timer: This timer define the number of sampled need to be executed per. Add 1. If you want to run parallel requests - just increase the number of threads in the Thread Group to reach the desired concurrency. JMeter cannot send requests faster than your application is capable of responding. Assuming there is only one request (sampler) in your Thread group and you are using the setting "All Active Threads" in. (2) Throughput Controllers to distribute the load in Percent [20% and 80% of total 24. One widget at a time is passed through a machine that stamps it with a label. This will ensure that request is made minimum 100 per minute. It pauses the execution of test for a specified. can only pause the threads to limit the throughput (requests per minute) to the desired value. Sorted by: 0. A Constant Throughput Timer will look like the picture above. Try running your test with 1 virtual user. 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. If there are more threads than values, the values get re-used. Very silly mistake with a conclusion: Check your throughput value, test for longer periods. A s the name suggested, Uniform Random Timer is used to generate the random delay in a uniform manner. 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. You could make the target throughput a variable too. Constant Throughput is a. 1 Answer. GitHub Repo: has mentioned that constant throughput variable value can be changed using a JavaScript or BeanShell function to provide a changing value. Request Oriented Goal: In such types of goals, we need to achieve the defined number of requests in an hour. JSR223 Timer. . JMeter also provides a timer component, ‘Constant Throughput Timer’, which you can use to set the value of Transactions per. e. You can have one HTTP header manager at Thread level or none (as per request type). You can add this element to your test plan by following “ Thread Group -> (right click) -> Add -> Timer -> Constant Throughput Timer ” path. Example 1: you have submitted a request and it returns "pending" status. How to add "HTTP Cache Manager" element? You can follow the below steps: 1. control. Use CTT in Test Plan level,not in thread group level. Now if you want to control the rate of transactions per second or the number of samples to execute you can use Constant Throughput Timer. 可以使用常数 吞吐量定时器 ( Constant Throughput Timer )来实现。. Go back to the "Test Plan" node. Constant Throughput Timer : The Constant Throughput Timer is like the Precise Throughput Timer, except that it has fewer settings. Constant Timer. Constant Throughput Timer (bộ hẹn giờ thông lượng không đổi) được sử dụng như một yếu tố định hướng mục tiêu giúp đạt được thông lượng mong muốn (tổng số yêu cầu). some examples are Constant Timer, Constant Throughput Timer. Nested classes/interfaces inherited from interface org. Component Properties - Properties that contain information about the duration and. The constant throughput timer delays the request to ensure that JMeter does not perform more requests than specified. 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. org; The function of timers is to delay the requests. I'm thinking that in my overall Test Plan, I will add all the a). If your goal is to mimic real users behavior as close as possible -. Timers can only pause JMeter samplers execution rate in order to limit JMeter's throughput to the desired value so you need to supply sufficient number of threads in the Thread Group. Other timers may impact constant throughput timer target, so it is recommended not to use other timers. Try using Constant Throughput Timer. Constant Throughput Timer: Java 8 incompatibility #3368. Select it and you will see 3 fields as below. Share. Below you will find a categorized list of the most common timer elements included with JMeter. So if the server could not manage the load, it results in minimum throughput. In case of throughput; the higher the better. Constant Timer with a Thread Delay of 5 milliseconds. And to manage throughput per minute you could use "Constant Throughput Timer". This capability is really helpful for debugging tests in real time. 2. In some cases, the Timer is used to implement the Pacing. Constant throughput timer is used to control the execution of requests according to the specified throughput. If there are 10 threads and a ramp-up time of 100 seconds, then each thread will begin 10 seconds after the previous thread started, for a total time of 100 seconds to get the test fully up to speed. 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. Despite its name Constant Throughput Timer doesn't have to be "constant", you can define throughput default value using __P(). Please suggest what should be the workaround of it? 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, another Thread Group, using JSR223 Test Elements, etc. All of the "Timer" group of elements affect the script. This blog post answers this questions and helps you build a JMeter test, step by step, to try it out. 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. 4. The easiest way of controlling the number of requests per second (throughput) in JMeter test is using Constant Throughput Timer. 0. Follow answered Nov 2, 2022 at 4:51. Constant Timer. Simply set the wait_time = constant_throughput (0. 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. There are 2 important elements which help to emulate the goal-based scenario when the number of requests is known and the target to achieve. For Constant Delay Offset of 3000 ms and Deviation time of 300 ms, each thread of JMeter would execute after {3000+(0-300 ms (could be any value between 0-300 ms)}. JMeter has a group of elements, which are called “Timers”. Also, JMeter tries to set the throughput per minute, so tests should be longer then 1 or 2 minutes with that timer. Doing the math, it should send a request every 5 milliseconds, and being 200 Threads, it should send 200 requests/second (200*5 = 1000ms). 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. 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. g. So your approach with different Thread Groups is valid. Move the Constant Throughput Timer under the request. Open your JMeter script and right click on Thread Group. The Constant Throughput Timer. 目标吞吐量（target throughput)单位是每分钟发送的请求数. Sorted by: 0. Constant Throughput Timer with a target throughput of 12000. Ramp-up is the time for JMeter to kick off the virtual users from point 1. In-depth Analysis: Throughput Controller in JMeter and Splitting Threads to Requests. Do not include multiple CTT in your test script as it will lead to a hoax. As per documentation>. 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. TestElement. 1 Answer. Built-in Constant Throughput Timer; Throughput Shaping Timer from jmeter-plugins. 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 Timer at Thread Group level. Since: 4. 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. 1. 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. JSR223 Timer. This is "closed workload" approach, and it has major drawbacks (see here why). Constant Throughput Timer pauses active threads to reach throughput level you define. Concurrency Thread Group doesn’t provide the ability to define initial delay, step transition and ramp-down - which the Stepping Thread Group does. HTTP is a stateful protocol, it means that JMeter's HTTP Request samplers wait for response prior to sending a new request so. Gaussian Random Timer. Constant Throughput Timer is available out of the box with JMeter. In JMeter, the ‘Timer’ element simulates the real user behaviour of taking a pause on a webpage. Two above would cover the majority of use cases, however if you want more control on your load pattern look into Throughput Shaping Timer (available through JMeter plugin) Share. 038. Its called JMeter Throughput Constant Timer. Ramp up 1 second for all. 作用：让jmeter以指定数字的吞吐量进行压测. 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. 1. In actual execution, in 1 hour. jsr223 request Constant Throughput Timer - 100 rpm. Hướng dẫn sử dụng Timer trong JMeter – Add Precise Throughput Timer 2. Concurrency can be controlled via Constant Throughput Timer or Throughput Shaping Timer and monitored via Server Hits Per. Uniform Random Timer 0. e. Concurrent users are a different way of looking at application traffic. This is "closed workload" approach, and it has major drawbacks (see here why). The timer tries to produce a constant throughput till the end of the test to achieve the target. Click on Constant Throughput Timer; This timer has the following fields,. In case of scenario 2 you'll need Constant Throughput Timer. Given you have Loop Count set to 1 JMeter will shut down. Given you use Concurrency Thread Group it makes more sense to switch to Throughput Shaping Timer which can be connected to the Concurrency Thread Group. 6 requests per minute or 2. 1. thread numbers, target throughput and what kind of information needs. e. 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. Ultimate Thread.
