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. (2) Throughput Controllers to distribute the load in Percent [20% and 80% of total 24. Click Add –> Timer –> Constant Timer. The constant timer pauses the test execution for a constant period. this is how you can control for how long JMeter threads are allowed to run. Click Add –> Timer –> Constant Timer. JMeter Constant Throughput Timer is used as a goal-oriented element which helps to achieve the desired throughput. Using JMeter, the constant throughput timer is particularly useful for this. Nested classes/interfaces inherited from interface org. A Constant Throughput Timer will look like the picture above. 4 requests per minute, it can be done 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. This way, You can use constant throughput timer in your load test plan to. JMeter cannot send requests faster than your application is capable of responding. So the real throughput depends on 2. A user logs in, goes to the main page, searches for a product, sees. The Uniform Random Timer pauses the thread by a factor of: The next pseudorandom uniformly-distributed value in range between 0. Try running your test with 1 virtual user. Constant Throughput Timer. e. In. This is what we need to control request frequency. The constant timer has the following components. See Also: Serialized Form. 1 Answer. 1 Thread Group. Concurrency depends on your test plan and application response time. 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). 目标吞吐量（target throughput)单位是每分钟发送的请求数.

Each having its own constant throughput timer . 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. 2. These timers will pause the threads and try to achieve the specified throughput value. 0 (exclusive) Multiplied by “Random Delay Maximum”. The total number of threads in the Ultimate Thread Group will be 250. Add Synchronizing Timer to the request and set Number of Simultaneous Users to Group by to X. The time is calculated from the start of the first sample to the end of the last sample. Bạn sẽ nhập 1 giá trị ngẫu nhiên vào Constant Timer thay vì giá trị cụ thể. First of all, Constant Throughput Timer can only pause JMeter threads in order to limit JMeter's throughput to the desired value. 2. Constant throughput timer (Timer) jmeter; Share. 0 requests/minute is saved as 0. JMeter Throughput by Example. . Nested classes/interfaces inherited from interface org. I am trying to configure a test for signup-login with invalid credentials imitating bruttforce attack. Constant Throughput Timer is used for pausing the threads to slow down overall execution speed to reach the target throughput. Given you have Loop Count set to 1 JMeter will shut down. JMeter provides lots of ways to record the value of throughput. e. Both thread groups are sending particular REST requests at a certain throughput using a constant throughput timer. 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. jmeter_loc – the full path to the root jmeter folder. Other timers may impact constant throughput timer target, so it is recommended not to use other timers. For different time of the day I'd use a different throughput value. BSF Timer. I have given 7 transactions per minute with calculate throughput based on parameter as all active threads. If you want to send 1 request each 20 seconds - the same approach as for point 2 but Target Throughput will. Improve this answer. In JMeter, the ramp-up period defines the time period within which all the specified users get in running state. If the request took 1000 mSec, it will apply 4500-1000 = 3500 mSec as the pacing. 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. org. although the Timer is called the Constant Throughput timer, the throughput value does not need to be 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. In my GET Thread Group I have added a bean shell processor- to convert the access token into a JMeter Property via __setProperty() function. Add Constant throughput timer to the thread group as shown below. some examples are Constant Timer, Constant Throughput Timer. Given you have 200 threads and 300 seconds ramp-up time it means that JMeter will start 200 threads in 300 seconds. 3. A good position would be a direct child of the Thread Group. Constant Throughput is a. Do not select "This thread only" value for Timer added at root, as it will change the result. This will ensure that request is made minimum 100 per minute. 4 Constant Throughput Timer This timer introduces variable pauses, calculated to keep the total throughput (in terms of samples per minute) as close as possible to a give figure. 4. Constant Throughput Timer can only pause threads in order to limit JMeter's throughput to the defined value. 2. Constant Timer: To delay every user request for the same amount of time use Constant Timer. Sample Time of Sample 2 is 172 ms. 8K subscribers. 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. Select it and you will see 3 fields as below. -> Ultimate Thread Group: Start Thread Count-100 ->Startup time-120 ->Hold load for-120 ->Shutdown Time-60 -> Constant Throughput Timer- Target Throughput(1200/min). Uniform Random Timer The uniform random timer causes each thread to wait for a random time. Subscribe. Basic Timers: Constant Timer → the most basic timer type which adds a simple delay to your test with no other parameters. In this example, a Constant Timer with 15000 milliseconds is used for sleep time. e 300s. JMeter timers mainly include Constant Timer, Uniform Random Timer, Precise Throughput Timer, Constant Throughput Timer, Gaussian Random Timer, JSR223 Timer, Poisson Random Timer, Synchronizing. For example, if I set Constant Throughput timer throughput to be 60 per minute,. 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 -. Total no of transactions = 40 (100 requests) Duration = 5m i. Remember 2 things: Throughput Timer isn't able to create threads, it can only slow them down so make sure that. Adding extra node will add extra 200 TMP. 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. Any JMeter component needs to be placed according to JMeter Scoping Rules. GitHub Repo: that the most simplest ways to control throughput in your tests is using either standard "out-of-box" Constant Throughput Timer or custom Throughput Shaping Timer from jmeter-plugins collection. I think the documentation was before Ultimate Thread Group was introduced. 1 Answer. 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. JSR223 Timer. Other (and the main factor) is your application response time. 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. La principal diferencia entre estos dos temporizadores esta en que el CTT inserta un pausa constante mientras que el CTT. 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. The test run may be shorter as if. Let’s think about an end-to-end scenario for an e-commerce website. Every timer has its own usability. Follow. What are Samples in JMeter? It generates one or more sample results. This will add Constant Timer at Thread Group level. 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. This would allow you to adjust it via Command Line in real time, as the test script is being executed. Constant Throughput Timer can only pause the threads to reach specified "Target Throughput" value so make sure you provide enough virtual users (threads) to. Throughput Controller - You can set the Max number of executions, OR the Percentage of executions of the sample (i. Follow answered Oct 22, 2015 at 16:42. Constant Throughput Timer. according to your application design you can retry this. So the Sample 3 should start at the time is 22:05:07. Pre Processors: allow you to perform operations/actions before. 2. Introduction. Gaussian Random Timer. The following is the list of JMeter 4. – EBDS. If you look at JMeter's Thread Group you will see Specify thread lifetime input:. If it is added under a sampler then the parent sampler will wait for the defined time. It is not even reaching 14 (well, except once)Irrespective of how much time the previous request took, it will apply the remaining time. The test plan currently uses two thread groups and runs those in loops. Target throughput (in minutes): 3000. . Constant Throughput Timer is precise enough on minute level so you might need to adjust your ramp-up period or consider using Precise Throughput Timer instead Constant Throughput Timer can only pause the threads to limit JMeter's requests execution rate to the given value so make sure to supply sufficient amount in the Thread. 30. JMeter – Constant Throughput Timer. thread numbers, target throughput and what kind of information needs. 可以使用常数 吞吐量定时器 ( Constant Throughput Timer )来实现。. referenced in the file. I just want to fix requests fired per second. Name Email Website. We would like to show you a description here but the site won’t allow us. As per JMeter Glossary: Throughput is calculated as requests/unit of time. ${__P(throughput)}. Apache JMeter is an open source Java based tool that enables you to perform functional, load, performance and regression tests on an application. 1) with Constant Throughput Timer value as 1200/min with "All active threads" and Timer added at the root of script. Constant Timer. 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. Debug sampler throughput can go more than 100000/sec. Download. i can see response times over 40 seconds. Assuming there is only one request (sampler) in your Thread group and you are using the setting "All Active Threads" in. 6 transactions per minute. ramp up to 6000 samples per min and so on up to 20000. We know that JMeter is an open-source, free tool used to conduct load and performance testing on static and dynamic web applications. Beanshell Server, check out How to Adjust the. Right click on "Test Plan" node. You can add this element to your test plan by following “Thread Group -> (right click) -> Add -> Timer -> Constant Throughput Timer” path. You can try setting the number of threads to i. Dmitri T. 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. Go back to the "Test Plan" node. If you get response times comparable to what you see in Fiddler. Constant Throughput Timer with a target throughput of 12000. 3. If you server is able to respond in constant response time then throughput will remain the same for a given number of clients (threads). e. e. In case you have only 1 request as in your scenario then it will generate Throughput of 20 request/sec (sometimes 20. If you set its value as “1. If Ramp-up Period is the time taken by JMeter to create the number of threads per iteration and if the duration of the test is 50820 seconds, then I should have 508200 samples only ( 50820/10 * 100 ). Gaussian Random Timer. With Constant Throughput Timer you can only pause JMeter throughput (number of requests per minute) to the desired rate but it works precisely enough on minute level, if you need second-level. 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. I have a requirement that in ultimate thread group , constant throughput value needs to be changed for every 5 mins using beanshell pre-processor. Use Throughput Shaping Timer. What is throughput time in JMeter? Throughput is calculated as requests/unit of time. If there are more threads than values, the values get re-used. JMeter now supports. I am adding throughput timer but then I need to set up. The constant timer is the basic timer among all the given ones. Follow asked Oct 26, 2019 at 10:10. A s the name suggested, Uniform Random Timer is used to generate the random delay in a uniform manner. Constant Throughput Timer is the easiest of built-in test elements, 2 requests per second is 120 requests per minute. The first request wil receive the correct amount of throuhput the first time, and so will the 2nd request. To apply a timer to a single sampler, add the timer as a child element of the sampler. The Uniform Random Timer pauses the thread by a factor of: The next pseudorandom uniformly-distributed value in range between 0. Below timers are used to implement pacing in Jmeter to achieve the desired load/Business transactions. Throughput Shaping Timer Properties. By default each JMeter thread executes samplers as fast as it can. Constant Throughput Timer will be enough for your scenario. 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. “Calculate throughput “ option can be varied based on the current thread, all threads in your test plan. 5. My website's expected performance is 200 concurrent users at 8 RPS. 0. Throughput, essentially, is the. apache. JMeter understand Thread Group / Throughput and INCLUDE. Add Constant Throughput Timer . 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. Add two entries to the "User Defined Variables. If the request took 1000 mSec, it will apply 4500-1000 = 3500 mSec as the pacing. Different Thread Groups having different number of threads; Throughput Controller; Switch Controller or Weighted Switch Controller plugins. JMeter cannot send requests faster than your application is capable of responding. Set Target Throughput = 40. I think you need to consider switching to Constant Throughput Timer, 100 transactions per hour == 1. 0 (inclusive) and 1. Share. Oct 10, 2022 at 7:06. Built-in Constant Throughput Timer; Throughput Shaping Timer from jmeter-plugins. I also changed the heap variable to this and i have a virtual machine with 32. Constant Timer or Gaussian Random Timer or Uniform Random Timer or whatever. So overall 20 users - ramped up in 1 seconds. However it is precise enough only on "minute" level so you might need to play with ramp-up period. Por ejemplo, cuando necesitamos mantener el servidor bajo cierta presión durante mucho tiempo, podemos controlar el rendimiento a través de este temporizador. Now, add the Constant Throughput Timer. Khi đó bạn sẽ cần sự trợ giúp từ hàm _Ramdom của JMeter. 4. Poisson. 3. If the machine stamps sixty widgets in one minute, it’s throughput is one widget per second. Precise Throughput Timer: siêu phức tạp, mình sẽ tìm hiểu rồi viết sau (hên xui) IV. JMeter Properties are global, can be accessed from different thread groups and persist all the time while JMeter is running. 2. Throughput Shaping Timer. Share. Throughput Shaping Timer. Throughput Shaping Timer. java:131. When you need to add a delay based on an edge condition which is not covered by other timers i. The JMeter docs in 3. 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. So your approach with different Thread Groups is valid. Share. You are right that Concurrency Thread Group is missing features of Stepping. 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. That means 40 samples has been executed in 1 minute. You can add this element to your test plan by following “ Thread Group -> (right click) -> Add -> Timer -> Constant Throughput Timer ” path. Do not include multiple CTT in your test script as it will lead to a hoax. Precise Throughput Timer: siêu phức tạp, mình sẽ tìm hiểu rồi viết sau (hên xui) IV. 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 think that you're misusing Constant Throughput Timer. Ori Marko. Alternative options are: JMeter also provides a useful timer component to configure or set a constant throughput value to test the application load. 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. In planning our load tests, our goal is often to measure whether or not our application (not just the. Constant Timer at Thread Group level. This video features #Constant #Throughput Timer in. Poisson. I would say that these timers are mutually exclusive. So the scenario is the next: Attempt to log in with invalid params in a loop. JMeter. 1 Answer. 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. Here, we’ve added a Constant Timer with a Thread Delay of three seconds to our thread group. 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. In addition, these timers are used for simulating the real user think time. JMeter Constant Throughput Timer Example. 0. 2. 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. 1. I ended up using constant_throughput to control the number of requests per second. Also, JMeter tries to set the throughput per minute, so tests should be longer then 1 or 2 minutes with that timer. Constant Throughput Timer is only capable of pausing JMeter threads in order to limit the number of requests per second to the given value. Figure 01: JMeter Timer Elements Scope of JMeter Timer: 1. Throughput Shaping Timer is a plugin and you need to install the plugin. 7. （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. 3. And to manage throughput per minute you could use "Constant Throughput Timer". Built into JMeter, there are 9 different types of timers available: . variable variable. So basically throughput is the number of requests which JMeter was able to within test duration time frame. 1 Answer. The JMeter Timers available are as follows: BeanShell Timer. That means 40 samples has been executed in 1 minute. And if you changed load generator machine or server. The main goal of. 0. But if I place my requests in separate Thread Groups - Throughput Controller doesn't work. 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. Synchronizing Timer 同步定时器. e. 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". 1). I am searching how to increase the number of sent requests per second . This would allow you to adjust it via Command Line in real time, as the test script is being executed. It will introduce the random relays between requests in such a way that required throu. Constant Throughput Timer: Constant Throughput Timer presents random delays between requests in a manner that a load/stress of necessary throughput is sent to the application. This is "closed workload" approach, and it has major drawbacks (see here why). Oct 10, 2022 at. Hot Network QuestionsThe formula is: Throughput = (number of requests) / (total time). Despite its name Constant Throughput Timer doesn't have to be "constant", you can define throughput default value using __P(). Constant Timer: 5000 ms (as configured) End Time of this sample is = 22:05:01. Constant Throughput Timer added with throughtput = 10 and Calculate Throughput based on = all active threads. e. 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. If you want to limit JMeter's throughput to 1100 requests per minute consider using Constant. JMeter sends specific types of requests to the server; with the help of samplers, the thread group decides which request is required to. 3. Sorted by: 0. 1 % of the load and 1 trying to generate. Uniform Random Timer. For example, a Bean shell timer is usually used to give delay time or think timer in between sampler requests. We highly recommend using the Uniform Random Timer. org; The function of timers is to delay the requests. 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. Constant Timer adds "think time" between requests, if you add the timer at the same level as all requests (see JMeter Scoping Rules for more details) - it means that JMeter will "sleep" for 2 seconds before each Sampler in the Timer's 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. HTTP Cache Manager must be included in your test plan if you have enabled your HTTP sampler to “Retrieve All Embedded Resources”. Target throughput (in samples per minute) value lets you manage the frequency for your requests. 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,. With Constant Throughput Timer, it sends more than 'n' requests per second. 12. This timer generates Poisson arrivals with constant throughput. 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 group elements are the beginning points of any test plan. I have used "jp@gc - Throughput Shaping Timer" But unable to achieve expected TPS. 7 requests per second. jmeter. Debug sampler throughput can go more than 100000/sec. If you need to test your system at 3500 requests per second you need to use slightly different approach, to wit add Constant Throughput Timer to your Test Plan and configure it to limit JMeter requests rate. 1. 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. 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. 2. Test execution result will looks like below for constant throughput timer jmeter example. Constant Throughput Timer: This 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. Gaussian Random Timer. Response Assertion. Nested Class Summary. Given your setup the only way of having exactly 399600 samplers is using Throughput Controller in. Remember 2 things: Constant Throughput Timer is precise enough on minute level, make sure your test lasts long enough so it could be. I have been trying to use JMeter to test my server. How to Use “ Constant Throughput Timer ” in JMeter. I have to test if it can scale upto 25000 requests per second without failing. In JMeter, there are 9 different Timer types. BSF Timer. Throughput Shaping Timer per se can only pause JMeter threads to limit execution rate to the given number of requests per second. Uniform Random Timer, Constant Throughput Timer, Synchronizing Timer, Beanshell timer,. Actually I use a constant throughput timer to keep the frequency constant. In Gaussian and Poisson random timer, the random number generation is based on the pre-defined function, but in the. Inside each thread group I have one parent Transaction Controller and a Constant Throughput Timer, trying to keep the total generated load of the Thread Group at 2 Transactions per second; Underneath the transaction controller, I have 2 child Throughput Controllers: 1 trying to generate 8. Constant Throughput Timer. The following article provides an outline for JMeter Throughput. There is a Constant Throughput timer, which as far as I understand, is to control throughput for individual requests. It seems that the Constant. See How to use JMeter's Throughput Constant Timer for details. Throughput Shaping Timer. Introduction. Solution 1: You can use Stepping Thread Group (allows to set thread number increase stages over set periods of time) with Constant Throughput Timer in it. Timer: By default, a JMeter thread executes samplers in sequence without pausing. 1. 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 . Here is my script detail:->Simple Login request. 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: acts precise enough on "minute" scale, if your test lasts less than minute it might not apply the throughput. 1. Constant Timer at Thread Group level. Share. 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. Throughput value in the Constant Throughput Timer can be changed to different values by using a variable. Trong bài này , ta chỉ tập trung vào Constant Timer thôi vì theo mình nó là đơn giản nhất. tgz (or whatever version you downloaded) Change into the unzipped directory: $ cd apache-jmeter-5. apache. Improve this answer. Thread Group 3. e. Based on RPS you want you can either set the value low for less number of requests and more for more RPS. 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. 0 and Calculate Throughput based on is all active threads. 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 Timer; Uniform Random Timer; Precise Throughput Timer; Constant Throughput Timer; Gaussian. 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. I ended up using a Test Action with 30s pause. Results: The JMeter Timers available are as follows: BeanShell Timer. 0” your throughput during the test will be 1 request per minute. はじめに. 3. Constant Throughput Timer cannot force threads to execute faster, it can only pause threads to limit JMeter's throughput to the defined value. iii. 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. 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. Another option is implementing pacing. Jmeter: Constant throughput Timer with Ultimate Thread Group. On top of that, it tries to maintain the exact amount of arrivals for a given timeframe ( throughputPeriod ).
