jmeter 10,000 concurrent users

JMeter has a decent set of Timers which can be used to help randomise the inter-arrival times of user actions. Because of the ‘Percent’ execution, out of 1000 concurrent users, 600 threads executed Sampler A and while others were sending request B. Pick the plan that works best for you. before starting the test. It’s important to get concurrency right because, ultimately, the workload is most likely being processed by some form of queuing system(s), and concurrency can affect arrival time on those queues. How large you can select the number of threads value on the client machine is dependend on many factors and you have to test it yourself, but since the purpose of JMeter is to see how your server handles X concurrent connections, I assume in many cases the server or the network connection to the server will be the limiting factor, not the local machine itself. We would call these fragments using Module Controller to avoid any redundancy. The weekend test is identical to the overnight run except that it lasts longer, and has a slower ramp up to the 10,000 users. 90% of total users on the application are searching for flights, 50% of them are new users – so they go through the registration process, 50% of them are existing users – they simply login and book the ticket, Login page is common for both regular and admin users, 10% of users on the application are admin users, 60% of admin users are modifying the flight as per the user request, 40% of admin users are cancelling the ticket as per the user request, JMeter – Creating Modular / Reusable Test Scripts, JMeter – How To Distribute User Load In The Test Plan. Only 90% of the users are actually searching for flight. You can use JMeter to analyze and measure the performance of web application or a variety of services. SteamDB shows there were 134,483 people playing Rust simultaneously yesterday -- a new record for the game, and almost 10,000 more than the 125,000 it reached in April. As I mentioned earlier, a high concurrent user test might not mean much if the majority of users are just idle, so throughput is just as important to model and effectively simulate. The number of unique visitors may be miscalculated. Other important metrics you should look at include throughput and errors. Or how http works. Concurrency contributes to, but does not define, overall workload. Default settings in the majority of commercial and open source testing tools are normally not enough to simulate a realistic workload model. This way you are not only able to estimate the numbers of users your web application can handle, but also where bottlenecks are and perhaps how to fix them. For example, the Response Codes graph will help show you non-HTTP 200 response codes. Performance tests with less than 10,000 concurrent users; Limitations of Using Real Browsers. In addition, they are also resource incentive. Too often, this period is discarded from test results. Published at DZone with permission of Tim Koopmans. Your email address will not be published. September 9, 2020, 9:50pm #4. How many users jmeter can support? Lets assume we already have created & verified the scripts for these business functionalities like Search / Login / Book etc. If NO, please suggest preferred technology. 40% of admin users are cancelling the ticket as per the user request; Test Results: I run the test for 100 concurrent users – Page visits have been distributed as per our requirement. Once the script is created & verified, user load has to be distributed in the test plan in such a way that it mimics the Production behavior. The popular JMeter Plugins library provides an alternative called the Ultimate Thread Group which, as its name implies, gives you more options for starting concurrent users. Posted 17-Jan-13 23:22pm. Beware of averages and uniform distributions. That is, we observed relatively flat response time profiles with little to no variation in results. in 1 thread group only test 1k user: Thread user = 1000, Ramp up = 10 ,is this means it will test 1000 user in 10sec?, Loopcount = 1, is there a disadvantage if I put 10 here ,is this means 1000x10 user = it will simulate 10k user? The Throughput Timer can also be useful as it introduces variable pauses, calculated to keep the total throughput (in terms of samples per minute) as close as possible to a given figure, which itself can be random. Lets assume that among 100 concurrent users. I have been trying to do some testing on my Moodle installation to estimate max number of concurrent users. 5:38. Concurrent Users: The word concurrent is used only for the events that occur over a period of time i.e. Never ignore Errors! This is because they consume more CPU and memory for JavaScript. I like to use the Gaussian Random Timer to randomly delay each request around a constant delay offset (according to Gaussian curve distribution). So, concurrency as a single measure lacks context. Apache JMeter allows you to manually configure the values of Number of Concurrent Users, Ramp-Up Time, etc. This provides a linear, uniform distribution for starting threads , so unless your objectives are to measure performance once all users have started up (and ignore startup itself) then this method is unlikely to simulate a realistic load profile . 2,000 users is typical for moderately complex testcases on modern hardware. The Apache JMeterTM is pure Java open source software, which was first developed by Stefano Mazzocchi of the Apache Software Foundation, designed to load test functional behavior and measure performance. A certain amount of effort/understanding is required to accurately model this. When i run the same test for 10000 concurrent users,  Page visits are still as per our requirements due to ‘Percent Execution’ option of Throughput Controller. JMeter also has a Test Action controller which I like to use to add a variable pause at the end of each iteration. If you assume N connections and M number of concurrent executions by connection, the more connections, the more overhead, more resources to do less and slower, For example, assume N = 10 and M =1000. In reality, there are a number of factors which contribute to workload and affect concurrency. See more: C#. For example, 12,000 unique visitors per hour / ( 60 minutes / 15 minutes per visit ) would equal 3,000 concurrent users. Or think times. They are thinking 50 Threads = 50 Users. JMeter - How To Distribute User Load In The Test Plan | Vinsguru A Poisson process, or the time between each pair of consecutive events, has an exponential distribution and each of these inter-arrival times is assumed to be independent of other inter-arrival times. Opinions expressed by DZone contributors are their own. In our previous post we pitted Gatling vs. JMeter in a side by side comparison, with concurrent load up to 10,000 users and found little to differentiate the product of each test. Tools like Google Analytics can help us in finding the frequently visited pages of our application & the percentage of user load among these pages. Most JMeter users prefer third party recording tools, which is not surprising. But there are no thread delays in the tests. JMeter originally is used for Monitoring for errors from the client side is extremely important to help track down potential bottlenecks on the server side. On a weekend, the automated test run, also tests using 10,000 concurrent users, but runs for approximaely 60 hours. We were defining SLAs based on the results. Skip to Main Content.
