I have been trying to do some testing on my Moodle installation to estimate max number of concurrent users. However, before you get too excited about the massive concurrency numbers you can generate with JMeter or any other popular load testing tool, have to think about what concurrency actually means in your test plan. Still, pacing between iterations can be difficult to get right, especially if you're aiming to simulate average visit duration, for example. More calculated methods might be to profile or trace real users over different periods or use descriptive statistics aside from the averages above to show a. I wrote a jmeter script, where thread count is 1000, ramp-up time is 1, loop is forever, duration is an hour. JMeter is a load testing tool which helps you to analyse the performance and scalability a web application. When I was last using JMeter, we were simulating 200 concurrent users and evaluating performance based on transaction times. Run Your Load Test for 10,000 Users We simulated JMeter for more and more threads . To simplify load scenario definition I would suggest using Ultimate Thread Group which provides easy and convenient way of setting start users number, time to hold the load, ramp-up and ramp-down times 4. 1000 concurrent threads do not mean 1000 concurrent users as real-life users don't hammer application as fast as they can, there are delays between requests called "think times". scenario 1 : - user login - request a welcome page Parameters : Thread Group : no. 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. I think an important not form that thread is 'Also JMeter concurrent threads are not "concurrent users" as real-life people do pauses between actions on web pages. Solution 1. First of all it is highly unlikely you will be able to spawn 100 000 virtual users using single JMeter instance so most probably you will have to go for Distributed Testing, it means that you will need to get several JMeter Slaves which will be orchestrated by JMeter Master; The number of virtual users which can be simulated from one host varies and depends on many factors, i.e. Concurrency is often used to define workload for load testing, as in concurrent users. Whizdom Trainings 1,263 views. Don't discard the results! Even if we had 1000 users, only 100 samplers were executed – remaining 900 threads have not sent any request as the Throughput Controller total execution limit has been reached already. Developers and DBAs get help from Oracle experts on: Emulating 10,000 concurrent users. Site Feedback; Sign In; Questions; Office Hours; Resources; About; Questions; Emulating 10,000 concurrent users; Breadcrumb. Thanks and Regards-Sameer. It does so by simulating multiple concurrent users browsing the web application. Hi all, I have been trying to do some testing on my Moodle installation to estimate max number of concurrent users. Visitors are more likely to follow some form of. The name of the controller seems to mislead – It does not actually control the throughput of the application server. With patience and a little wrist RSI plugging the information into the UI, you can create more realistic concurrent load profiles. I need to load test the web app, by simulating 1000 concurrent users. Over a million developers have joined DZone. I think you will find it useful what is the concurrent users in load testing using Jmeter. JMeter Load Test with 1,000,000 threads; JMeter Load Test with 1,000,000 RPS; JMeter Load Test with 10,000,000 Requests Per Minute ; While Flood can certainly support tests of this scale, we find most companies haven't given enough thought to what type of workload they really need to test with. I am going to divide Concurrent users load into two-part * Synchronizing Timer - pause threads unless a certain number will be reached and fire them all at the same time. Hence you need a software tool like JMeter that will simulate real-user behaviors and performance/load test your site. FWIW, I often find many performance related defects during ramp-up, especially with more realistic models for starting users. If I modify the test plan as shown below, that is, 60% of total threads will execute A. If you want to execute a Goal-oriented scenario where the target is not to simulate the number of concurrent users, but the number of requests per second then Constant Throughput Timer is best for such type of scenario. If it's 10,000 requests hitting a page you can cache/reverse proxy etc, and you've got sessions turned off by default, then sure, do-able with simple scaling and a load balancer. getting 1000 concurrent users is actually very hard to do on a single server. Rate this: Please Sign up or sign in to vote. If our requirement is to test the above application with 100 concurrent users, we can not distribute the load like 20 users per functionality. 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. Cost and complexity are two known limitations. We have a web CRUD app. 2,000 users is typical for moderately complex testcases on modern hardware. Subscribe to this blog. On a weekend, the automated test run, also tests using 10,000 concurrent users, but runs for approximaely 60 hours. Add a Solution. We had already published an article on Performance Workload Modeling using Little’s law. This site uses Akismet to reduce spam. 50% of 33.333% of total users are new users = 16.67%, 50% of 33.333% of total users are existing users = 16.67%, 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. Very useful, with this can replicate real user scenarios easily. Only 90% of the users are actually searching for flight. ; JMeter can discover maximum number of 10,000 concurrent users. That depends on the complexity of your test. Concurrency on its own is not enough to define system workload. Hi guys, 10,000 users watching VOD is a fairly large number of simultaneous customers for most (general content) providers, but it can be done using current technology. Throughput can be measured in many different ways, such as network throughput or the number of requests per second. 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. Rate this: Please Sign up or sign in to vote. For our requirement of above flight search application, I would be using Percent Execution option and per user checkbox would be unchecked – Because the percent is among all VUsers, Not per user. this blog has been moved here. Posted 17-Jan-13 23:22pm. Before even I found this forum, I started off using JMeter to do the testing, came to some conclusions and then came across the script "perspective.php" that has posted in this forum. Cost and complexity are two known limitations. That would be 10,000 concurrent queries. Monitoring for errors from the client side is extremely important to help track down potential bottlenecks on the server side. Translating samples per minute (as JMeter executed them) to your model's throughput targets can be difficult. Hi, I am using jmeter version 2.3.2. I have a requirement to check the response time and throughput of a single http request URL with 10000 Concurrent Users. Currently, I have all the test runs automated so that every night, a 10,000 concurrent user test is initiated that runs for approximately 12 hours. 200 concurrent users will first hit the home page 2. Forgive my possible ignorance here but we're looking to test a live stream using the load testing tool from Wowza. However we need to use appropriate controller to distribute the load to simulate production like behavior. It's not feasible to arrange 100 people with PC and internet access simultaneously accessing google.com Think of the infrastructure requirement when you test for 10000 users (a small number for a site like google). For up to 100,000 requests per second most modern servers are fine, but take a note, that there may be issues with NIC (you should choose server hardware wisely - 10 GB NIC recommended) and … Marketing Blog, The assumption that visitors are spread evenly across the 1 hour period sampled. 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. But in the actual test plan, we need to keep group the samplers based on the user action on the application using Transaction Controller. Performance test engineers use JMeter to perform performance testing. After that 200 concurrent users will hit the products page 3. 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. Concurrency in Flood IO is the number of active threads for all thread groups in your test plan. Re: Moodle Hardware for 10,000 users and 300 users concurrent(at the same time) by Usman Asar - Friday, 30 October 2015, 7:13 PM Then either get an HP Proliant like Visvanath mentioned, or Dell Optiplex will do as well, or best off built one yourself, get a Super Micro Motherboard for AMD Opetron 6272, its 16-core CPU will cost you as same as buying a XEON with 6 core, cheap and simple. Assuming you've shaken out your JMeter scripts standalone, you can also run them on Flood IO using free nodes to get a feel for available reports. 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. In this article, Lets see how we can distribute the load across the critical scenarios of the application using Throughput Controller in JMeter. The following are the few customizations one needs to do before using it: 1. It helps us to simulate numbers of Hence the users which are running under a test plan; irrespective of the activities they are doing; are ‘Concurrent Users’. 2 JMeter can be used to test the performance of both static resources such as JavaScript and HTML, as well as dynamic resources, such as JSP, Servlets, and AJAX. If you want to execute a Goal-oriented scenario where the target is not to simulate the number of 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. As a result, we found that the max value of users we could simulate was around 8000-9000 users. For example, the Response Codes graph will help show you non-HTTP 200 response codes. Far too often testers don't know the difference between logged in users and concurrent users. Because of the ‘Percent’ execution, out of 1000 concurrent users, 600 threads executed Sampler A and while others were sending request B. before starting the test. 6 tips to prepare your NodeJS app for heavy production load | … Is that possible to simulate 1000 to 10000 user to jmeter? For up to 10,000 requests per second most modern servers are fine. While I was browsing for documentation on the topic, I found a sample JMeter plan specific for Drupal on Drupal Performance Testing Suite’s page. Notify me of follow-up comments by email. Use Case Scenario – Concurrent Load Testing. It does so by simulating multiple concurrent users browsing the web application. If you don't set any pauses in your tests then 20 concurrent threads will stand for something like 200-250 concurrent users.' With LoadView, there are a variety of ways you can conduct a concurrent user test. Note: % in the below diagram shows the % of total users who accessed the application. Yes some one asked above. 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. Published at DZone with permission of Tim Koopmans. Apache JMeter testing tool offers following benefit in Performance Testing. How to calculate the network speed. Performance tests with less than 10,000 concurrent users; Limitations of Using Real Browsers. This information provided by the tool needs to be thoroughly reviewed by Performance tester with the help of Business side Product owners / Project managers / BA / Application Architect etc to confirm the scenarios to be tested and user load distribution. JMeter is a powerful open-source Java application with a wide variety of features, which makes it daunting to set up a test plan in it. There is a good thread on this topic here that I have used for my reference. Appreciate your … Take advantage of our more than a decade of experience to quickly find the solutions to your performance problems. Or how http works. Most JMeter users prefer third party recording tools, which is not surprising. JMeter originally is used for Before even I found this forum, I started off using JMeter to do the testing, came to some conclusions and then came across the script … The test plan was - 1. ThreadGroup holds the settings for a JMeter thread group. Hi, It seems that what you’re trying to do is launch 10000 transactions at your server at a rate of 1 tx/sec. For N = 1 and M = 10000 that would be also 10000 concurrent queries. Thanks for sharing. A simple 6 web page test with images and think time between pages consumed 90% of the CPU at only 50 concurrent users. At the heart of JMeter is a Thread Group, which lets you define how many users, a ramp-up period, and either the number of times to execute the test or a fixed duration for the test. 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. John_West. I run the test for 100 concurrent users – Page visits have been distributed as per our requirement. I like to use the Gaussian Random Timer to randomly delay each request around a constant delay offset (according to Gaussian curve distribution). Pick the plan that works best for you. Higher load is not actually anticipated on the target web site in production. Throughput controller has below options to control the execution of the samplers. Yes, I am in an argument with a client about this fact. I create a Test Plan like this with 1000 concurrent users. While I was browsing for documentation on the topic, I found a sample JMeter plan specific for Drupal on Drupal Performance Testing Suite’spage. i am using jmeter, to do the load test. There should be a sampler for Search request. That's probably not as bad as 10,000 actual concurrent *logged in* users generating all sorts of stuff. What were those users actually doing? When it comes to parameterization and correlation, you can do this, but with no automation and you will need to know really well what you are doing, because even to extract a single value between two boundaries, you will need to use regular expressions. of threads, and the engine capacity gets chosen automatically. The following figure shows how the plan document looks.
