Let’s think about an end-to-end scenario for an e-commerce website. TestElement. 3. JMeter has a group of elements, which are called “Timers”. Para poder realizar esto utilizando solamente JMeter, se encontró que el único elemento que permite modificar el throughput en tiempo de ejecución es el Constant Throughput Timer. BSF Timer. If you want to send specific amount of requests during this hour consider using Constant Throughput Timer, but be aware of the following:. Doing the math, it should send a request every 5 milliseconds, and being 200 Threads, it should send 200 requests/second (200*5 = 1000ms). JMeter – Constant Timer. Go back to the "Test Plan" node. Constant Throughput Timer added with throughtput = 10 and Calculate Throughput based on = all active threads. 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. 6 requests per minute or 2. Uniform Random Timer. Có rất nhiều timers được cung cấp trong JMeter: Constant Timer, Gaussian Random Timer, Uniform Random Timer, Synchronizing Timer, etc. e. It is not even reaching 14 (well, except once)Irrespective of how much time the previous request took, it will apply the remaining time. I have tried JMeter with a constant throughput timer with throughput = 1500000 per second and running 1000 threads. Built into JMeter, there are 9 different types of timers available: . 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. 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. If your script keeps hitting timeouts and includes these elements, remove or disable them unless they are important for your functional test scenario. 4. Gaussian Random Timer. Uniform Random Timer 0. Constant Throughput Timer. 0. Constant Throughput Timer – introduces variable pauses, calculated to keep the total throughput as close as possible to a given figure. JMeter™ User Save time for the Thread Groups creation. although the Timer is called the Constant Throughput timer, the throughput value does not need to be constant. 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. First of all, Constant Throughput Timer can only pause JMeter threads in order to limit JMeter's throughput to the desired value. 3. JMeter has a group of elements, which are called “Timers”. JMeter now supports. 30. 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. Adding a constant timer on a transaction. "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. X * Random Delay Maximum + Constant Delay Offset| where X an be the. Nested Class Summary. apache. 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. How to Use “ Constant Throughput Timer ” in JMeter. 2. e. Running Jmeter script by targeting 1000 requests per second (Business SLA) hence used 'Constant Throughput Timer' or 'Throughput shaping timer' as suggested in below queries. How do I achieve a certain TPS in Jmeter. Summary Report I have tried 2 ways: Instead of simple controller, i have used throughput controller and used percent Executions. This plugin is specially designed to schedule RPS loads. A JMeter Timer is a built-in plugin tool for JMeter that can help with spacing out your sample requests. Beanshell Server, check out How to Adjust the. Precise Throughput Timer → this timer will vary its delay interval to keep requests at or below a certain threshold. Throughout the Hold Load time(180sec) the requests will be looped. Also, JMeter tries to set the throughput per minute, so tests should be longer then 1 or 2 minutes with that 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. If you want to run parallel requests - just increase the number of threads in the Thread Group to reach the desired concurrency. 0. 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. I ended up using constant_throughput to control the number of requests per second. Constant Throughput Timer The constant throughput timer is a special type of timer used to create pauses. คอร์สนี้จะพาทุกคนไปรู้จักกับ JMETER (Tool ที่ดีที่สุดสำหรับการทำ Performance Testing) ตั้งแต่เริ่มลงโปรแกรม ไปจนถึงการใช้งานชั้นสูง. My test config in jmeter. Timer: By default, a JMeter thread executes samplers in sequence without pausing. If you want to slow down JMeter to the desired number of requests per minute it can be done using Timers. And run the following to. Based on RPS you want you can either set the value low for less number of requests and more for more RPS. You may need to try it out in a few runs to find the optimum value of sleep time to get the desired throughput. 1. I just want to fix requests fired per second. Relation between Constant throughput timer, transactions per sec and throughput in summary report 0 How to get number of throughputs per second as 500 in jmeter54. If you introduce artificial delay of 3 seconds - it will make the overall throughput lower. So your approach with different Thread Groups is valid. When the throughput is saved to a CSV file, it is expressed in requests/second, i. Go back to the "Test Plan" node. I am developing a JMeter Script according to the below requirement. If it is added under a sampler then the parent sampler will wait for the defined time. Simply set the wait_time = constant_throughput (0. 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). In case you have only 1 request as in your scenario then it will generate Throughput of 20 request/sec (sometimes 20. BSF Timer. Throughput timer is in root of test plan, Where as other timers are only applicable within scope of controllers. is correct, but if you leave it as is JMeter will execute requests as fast as it can. I also had constant. With 100 threads you will get 50 requests per second. How to calculate. jmeter_loc – the full path to the root jmeter folder. You can consider switching to Concurrency Thread Group and Throughput Shaping Timer. e. 0. jmeter. 1. 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. 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. 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. Remember - if the application itself is not supporting the desired throughput, jmeter can not help here. Improve this answer. Select it and you. either execute this 100 times OR. 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. Start RPS End RPS Duration 1 10 3600 2 4 3600 2 8 3600 Total Number of Users- 300 ; Ramp Up 600 Seconds ; Duration of Test 10800 Seconds. Actually I use a constant throughput timer to keep the frequency constant. This will ensure that request is made minimum 100 per minute. 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. However, in one case I need an additional constant timer because I need to wait a certain time between two requests. The Uniform Random Timer. Example 1: you have submitted a request and it returns "pending" status. I want to measure the response time of this 100 users login which I've. And if you changed load generator machine or server. 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. It is often the first step to develop test plans for applications. Use Cases. Step 2. 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. Constant Throughput Timer can. The achieved target may be slightly high. Now, add the Constant Throughput Timer. Constant Throughput Timer. Also be aware that: 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. JMeter Constant Throughput Timer is used as a goal-oriented element which helps to achieve the desired throughput (Total Number of Requests). I also changed the heap variable to this and i have a virtual machine with 32. I have single thread group with 40 users. The various timers provided by JMeter include the constant timer, uniform random timer, constant throughput timer, Poisson random timer and Gaussian random timer. JMeter: Not enought delay between HTTP samplers. JMeter acts as follows: It starts all threads within specified ramp-up period. This plugin also works similarly to Constant Throughput Timer, which pauses the threads based on the target Throughput. The name that we have given is displayed on the tree and here. Testing without a JMeter timer can create irregular test results because the simulated requests will come in a different pattern than. A user logs in, goes to the main page, searches for a product, sees. jmeter. 0 Calculate Throughput based on: all active threads in current thread group So now, in 1 minute, JMeter will try to send 3000 requests and in 5 minutes, request count will be more or less around 15000. Ramp-up is the time for JMeter to kick off the virtual users from point 1. 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. Below screenshot is list of all Timers provided by JMeter to control the load. Plus “Constant Delay Offset”. The total number of threads in the Ultimate Thread Group will be 250. getMaxThroughputAsInt(ThroughputController. 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. a) To maintain a constant throughput rate b) To simulate real user behavior c) To generate random data d) To pause the thread execution Answer: a) To maintain a constant throughput rate Explanation: The Constant Throughput Timer in JMeter is used to maintain a constant throughput rate by controlling the number of requests per. Add Constant Timer as a child of the first request and configure it to introduce "sleep" for 30 minutes: in this case the delay will be introduced before first request, see A Comprehensive Guide to Using JMeter Timers article for more information. Share. 0. Constant Throughput Timer. Given here are some JMeter listeners that you can use for this purpose: Summary Report Aggregate Report Aggregate Graph Graph Results. TestElement. So overall 20 users - ramped up in 1 seconds. Throughput increased by factor of 2. Here are the workarounds: Calculate the number of threads you need to achieve your target. Doing the math, it should send a request every 5 milliseconds, and being 200 Threads, it should send 200 requests/second (200*5 = 1000ms). Add Constant Throughput Timer to your Test plan and configure it to send 30000 requests per minute (500 requests per second). Very silly mistake with a conclusion: Check your throughput value, test for longer periods. Test Case 2: - 6 requests per minute - 1 request each 10 seconds. 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. 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 Shaping Timer. This video features #Constant #Throughput Timer in. e. 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. All of the "Timer" group of elements affect the script. Try using Constant Throughput Timer. Follow answered Nov 2, 2022 at 4:51. Gaussian Random Timer. Any JMeter component needs to be placed according to JMeter Scoping Rules. Use 0 for truly random delays and a positive integer for constant. JMeter's Constant Throughput Timer can only capable of pausing the threads to limit the number of transactions per minute to the given value, if the current amount is not enough - it won't kick off extra threads. In case of scenario 2 you'll need Constant Throughput Timer. Let’s see how we can use constant throughput in JMeter as follows: With the help of constant throughput, we can keep constant time. We will conduct a sample load test with 100 concurrent users (threads) and evaluate the throughput value. 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. With Constant Throughput Timer, it sends more than 'n' requests per second. Nested classes/interfaces inherited from interface org. Below timers are used to implement pacing in Jmeter to achieve the desired load/Business transactions. Hướng dẫn sử dụng Timer trong JMeter – Add Precise Throughput Timer 2. throughput property as: ${__P(throughput,)} "tell". Constant Throughput Timer is used for pausing the threads to slow down overall execution speed to reach the target throughput. Constant Throughput Timer will let you control the flow of requests to be. Constant Throughput Timer. Target throughput (in samples per minute) value lets you manage the frequency for your requests. Constant Timer: To delay every user request for the same amount of time use Constant Timer. Precise Throughput Timer allows you to reach and maintain the desired throughput (number of requests per given amount of time) Gaussian Random Timer - allows you to simulate "think time". Test execution result will looks like below for constant throughput timer jmeter example. I am searching how to increase the number of sent requests per second . is correct, but if you leave it as is JMeter will execute requests as fast as it can. Do not select "This thread only" value for Timer added at root, as it will change the result. Constant Throughput Timer will be enough for your scenario. I have a cloudsearch endpoint on AWS. Dmitri T. Sorted by: 0. Constant Timer: 5000 ms (as configured) End Time of this sample is = 22:05:01. Also Constant Throughput Timer works on minute level and your desired throughput should be. Constant Throughput Timer is only capable of pausing JMeter threads in order to slow them down to reach the target throughput. This would allow you to adjust it via Command Line in real time, as the test script is being executed. N. In the JMeter script, Constant Timer is used to add a constant delay before processing a sampler. Use Precise Throughput Timer. 1). 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 think it will be more accurate than looking at locust's current_rps tracker, especially at low load. Download. Constant Throughput Timer is only capable of pausing JMeter threads in order to limit the number of requests per second to the given value. Constant Throughput Timer introduces variable pauses, calculated to keep the total throughput (in terms of samples per. You can add this element to your test plan by following “ Thread Group -> (right click) -> Add -> Timer -> Constant Throughput Timer ” path. JMeter timers mainly include Constant Timer, Uniform Random Timer, Precise Throughput Timer, Constant Throughput Timer, Gaussian Random Timer, JSR223 Timer, Poisson Random Timer, Synchronizing Timer, BeanShell Timer. JMeter Perfmon. If I disable the constant-timer, I can see all the request being made in the span of 1ms: Share. Tổng kếtConstant Throughput Timer is the easiest of built-in test elements, 2 requests per second is 120 requests per minute. Jmeter measures throughput by observing the. Despite word "constant" in its name, you can use i. Save my name, email, and website in this browser for the next. {"payload":{"allShortcutsEnabled":false,"fileTree":{"src/components/src/main/java/org/apache/jmeter/timers":{"items":[{"name":"gui","path":"src/components/src/main. Test Plan 2. 2. Test Plan. Throughput - the Throughput is measured in requests per second/minute/hour. If your scenario is to execute 100 requests evenly distributed across one minute you should rather go. During this Test(while loads are held) , I am sending another set of login requests from the different machine (say for 100 users). It pauses the execution of test for a specified constant amount of time. 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. La principal diferencia entre estos dos temporizadores esta en que el CTT inserta un pausa constante mientras que el CTT. Because 100 transactions per hour means one transaction each 36 seconds for 1 user and if you have 30 users the number will be proportionally less. Because JMeter sometimes displays throughput in per minute and sometimes in per second, whereas the hits per second is always per second. 目标吞吐量（target throughput)单位是每分钟发送的请求数. Constant Timer. ramp up to 6000 samples per min and so on up to 20000. 0 (inclusive) and 1. e. Timers provided in JMeter Constant Timer. If for some reason you need to proceed with JMeter take a look at Constant Throughput Timer which can limit requests execution rate to the desired value. 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. We know that JMeter is an open-source, free tool used to conduct load and performance testing on static and dynamic web applications. As per documentation: Set Target Throughput = 40. Constant Timer with a Thread Delay of 5 milliseconds. The constant timer is the basic timer among all the given ones. But if I place my requests in separate Thread Groups - Throughput Controller doesn't work. Since: 4. Tell JMeter to parse the HTML file and send HTTP/HTTPS requests for all images, Java applets, JavaScript files, CSSs, etc. so I used a ultimate thread group and set the threads to 200 and ramp up was 200seconds. Share. asked Mar 4, 2021 at 6:07. 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. Updated February 14, 2023. 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. Introduction. 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:. The Constant Throughput Timer. 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。. Constant Throughput Timer : The Constant Throughput Timer is like the Precise Throughput Timer, except that it has fewer settings. Constant Throughput Timer is available out of the box with JMeter. Constant Timer; Uniform Random Timer; Precise Throughput Timer; Constant Throughput Timer; Gaussian. Different Thread Groups having different number of threads; Throughput Controller; Switch Controller or Weighted Switch Controller plugins. Using JMeter, the constant throughput timer is particularly useful for this. So you need to supply the sufficient amount of threads in the Thread Group. Debug sampler throughput can go more than 100000/sec. This is what we need to control request frequency. 1. Uniform Random Timer. variable variable. Total no of transactions = 40 (100 requests) Duration = 5m i. The constant timer is one of the most widely used timers in JMeter. There is a Constant Throughput timer, which as far as I understand, is to control throughput for individual requests. 2. I think that you're misusing Constant Throughput Timer. Constant Throughput is a. java:131. Throughput Shaping Timer is a plugin and you need to install the plugin. Constant Throughput Timer can only pause the threads in order to limit JMeter to the defined number of requests per minute. This is the function of Constant Throughput Timer. So you creating the excessive number of threads and then the timer will. jmeter; performance-testing; Share. Here, we’ve added a Constant Timer with a Thread Delay of three seconds to our thread group. Right click on Thread Group > Add > Timer > Constant Throughput Timer. 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. 2. If you server is able to respond in constant response time then throughput will remain the same for a given number of clients (threads). Given you have the timer you produce less load so application has more chance to respond properly. What do you mean by "total transactions"? If you want to send 30 requests in 15 minutes more or less evenly distributed you need to use Constant Throughput Timer instead of the Synchronizing Timer and configure it to send 2 requests per minute. Second I would recommend checking whether your system under test has enough headroom in terms of resources (CPU, RAM, Network, Disk, etc. JMeter also provides a timer component, ‘Constant Throughput Timer’, which you can use to set the value of Transactions per. Concurrent users are a different way of looking at application traffic. Target throughput (in samples per minute) value lets you manage the frequency for your requests. Tool ที่เราใช้ในการทำ performance test ก็คือ JMeter ซึ่งเป็น tool opensource ที่เขียนด้วย Java สำหรับการทำ load test การจำลอง request จากหลาย user ที่เข้ามาพร้อมกันทำ. 2. 1 Answer. This is "closed workload" approach, and it has major drawbacks (see here why). Ramp up 1 second for all. This blog post answers this questions and helps you build a JMeter test, step by step, to try it out. 3. 0. 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. However, in one case I need an additional constant timer because I need to wait a certain time between two requests. 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. The JMeter Timers available are as follows: BeanShell Timer. 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. 1 Answer. 2. 2. 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. When you need to add a delay based on an edge condition which is not covered by other timers i. jmeter. Constant throughput timer is used to control the execution of requests according to the specified throughput. This class implements a constant throughput timer. Download. The main goal of. jmeter. Also its effect is not immediate so during 1st minute of your load test you need to control virtual users arrival rate using Ramp-Up Period setting on Thread Group level. 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. This timer tries to maintain a constant throughput throughout the test and achieve the target. All you need to do is to slow it down a little bit, one of the options is adding a Constant Throughput Timer. For different time of the day I'd use a different throughput value. Now check the time difference between the 1st sample and 11th sample, it is 1 minute. Hot Network QuestionsYou can slow down JMeter's number of requests per minute by using Constant Throughput Timer. I do not want to "pre-decide" what throughput I want. It is not necessary to have a separate HTTP header manager with each request unless request needs a unique header. Hot Network Questions Is there any way retirement systems can cope with declining population? Which verb fits in 庭に木をもう一本_？. Constant Timer or Gaussian Random Timer or Uniform Random Timer or whatever. 3. The. Constant Timer or Gaussian Random Timer or Uniform Random Timer or whatever. jmxaccording to jmeter manual ramp up is: How long JMeter should take to get all the threads started. Click Add –> Timer –> Constant Timer. I am using a Constant Throughput Timer with "Calculate throughput based on: all active threads in current thread group" selected. Constant Throughput Timer: acts precise enough on "minute" scale, if your test lasts less than minute it might not apply the throughput. The Throughput Shaping Timer plugin also adds a number of properties to the standard JMeter functionality: elementName_totalDuration is a sum of all durations from the Request Per Second Schedule. In both the cases structure of the test will be like the following:Be aware that Constant Throughput Timer is accurate enough on minute level so it can start pausing the threads only after 1 minute. Figure shows, Constant Throughput Timer for 60 requests per. B. 6. Given your setup the only way of having exactly 399600 samplers is using Throughput Controller in. Given here are some JMeter listeners that you can use for this purpose: Summary Report Aggregate Report Aggregate Graph Graph Results. The constant throughput timer delays the request to ensure that JMeter does not perform more requests than specified. Constant Timer) as a child of the 2nd request. it worked. Test execution result will looks like below for constant throughput timer jmeter example. 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. 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. JMeter – Constant Throughput Timer. Constant Timer adds a delay after the request completes (not after start), which doesn't fit either. So you need to supply the sufficient amount. 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。. This ultimate thread group will give you more control over Threads. Add two entries to the "User Defined Variables. If you want the throughput applied from the very beginning of your test you have the following options: Use longer ramp-up period in Thread Group. apache. answered Apr 20, 2014 at 16:43. HTTP Cache Manager must be included in your test plan if you have enabled your HTTP sampler to “Retrieve All Embedded Resources”. 线程组线程数设为10. Throughput shaping timer or CTT to control the expected throughput. QAInsights. We should see. HTTP Sampler for GET call is used. e. You can add this element to your test plan by following “Thread Group -> (right click) -> Add -> Timer -> Constant Throughput Timer” path. Constant Throughput Timer cannot force threads to execute faster, it can only pause threads to limit JMeter's throughput to the defined value. Constant Throughput Timer can only pause threads in order to limit JMeter's throughput to the defined value. Uniform Random Timer. However I fail to see how Constant Throughput Timer is connected with the timeouts because it slows the number of. This video features #Constant #Throughput Timer in #JMeter. รวมถึง. With 100 threads you will get 50 requests per second. Constant throughput timer (Timer) jmeter; Share. 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. If you get response times comparable to what you see in Fiddler. 4 requests per minute, it can be done using i. 1 Answer. 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. 0. Poisson Random Timer. Follow answered Oct 22, 2015 at 16:42. Step 3. So if the server could not manage the load, it results in minimum throughput. 1. Oct 10, 2022 at 7:06. 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.
