Performance Testing Process > Performance Testing Practice > SPEForums need your contributions to build up a strong repository of performance engineering resources. The more realistic your simulation, the more likely you'll catch bottlenecks that lead to a bad user experience. Below is the table of 5 users working in an e-commerce application. Concurrent = operating in same window of time, but each on an independent set of actions. Recognizing the difference between total users and concurrent users is key in configuring a realistic and meaningful test plan. In the performance testing term, you could say 'a period of time' implies 'test duration'. It helps in identifying and measuring the problems in system parameters such as response time, throughput, deadlock occurrence or any other issues related simultaneously. When configuring a test plan for our clients we want to establish a realistic number of concurrent users, in other words, the number of users actually in the system, actively using the application at a given time. Concurrent Users: The word concurrent is used only for the events that occur over a period of time i.e. Stack Overflow for Teams is a private, secure spot for you and Hence for a web site, the number of simultaneous users would be always greater than the concurrent users.For example , a banking web site has the workload of about 30000 simultaneous users & 5000 concurrent users. These are the 2 terms which is often used in Performance Testing. We could see that all the users are in the same search cart transaction denoted by x mark. How do you run a test suite from VS Code? It is also true that good tools that can test thousands of virtual users cost an arm and a leg. Ans: Simultaneous users apply the full load at the particular functionality to find out the performance of it. Simultaneous testing is a type of testing that is performed to identify the defects in a software, system and application when multiple users login to the respective application. Asking for help, clarification, or responding to other answers. Well-behaved load test has to represent real user as close as possible, otherwise it will not make a lot of sense to run such a test. Whenever someone asks us how many concurrent users they “should” use in a test to understand their performance baseline and prepare for a big wave of traffic, we like to follow a … "Hourly Sessions x Average Session Duration (in seconds) / 3,600" is the formula we recommend to get started It’s always good to take the guesswork out of your load testing and test … How does SQL Server process DELETE WHERE EXISTS (SELECT 1 FROM TABLE)? Simultaneous = users executing the same code at the exact same time. Why server CPU usage reaches to 100% with only 25 concurrent users? On the other hand simultaneous vusers is more to do with rendezvous points. They are thinking 50 Threads = 50 Users. How is the Ogre's greatclub damage constructed in Pathfinder? In performance testing there should be only one term: virtual user which must represent real user, that's it. fly wheels)? These performance tests are very basic tests where there is only single HTTP request (per user). simultaneous = same action, same time. Transactions highlighted in Green are completed by the user and in yellow are yet to be started which also differs from user to user. Example: Tatkal reservation at IRCTC site Concurrent user testing is also called simultaneous user testing. Good or Bad? When we set rendezvous points we instruct the system to wait till a certain no of vusers arrive so that they all can do a particular task simultaneously. tl;dr — This post is about using Google Analytics to determine how many concurrent users to specify in your load tests.

Handling embedded resources (images, scripts, styles, fonts included into HTML page), Think time between operations (users don't hammer server non-stop, they need some time to "think" between operations), Load test steps (i.e. Transactions highlighted in Green are completed by the user … How to run web performance test for 200 users in VS 2013? Why is there no Vice Presidential line of succession? Key takeaways. "Concurrent users" in performance testing - limitations. Concurrent = users on the system using resources. Making statements based on opinion; back them up with references or personal experience. Session information (total number of sessions, average length of the sessions) is helpful in … Thanks for contributing an answer to Stack Overflow! Hence the users which are running under a test plan; irrespective of the activities they are doing; are called as 'Concurrent Users'. rev 2021.1.11.38289, Stack Overflow works best with JavaScript enabled, Where developers & technologists share private knowledge with coworkers, Programming & related technical career opportunities, Recruit tech talent & build your employer brand, Reach developers & technologists worldwide, Difference between Simultaneous and Concurrent users, the relationship between virtual users and server hits per second, Podcast 302: Programming in PowerPoint can teach you a few things.
