How many concurrent users is good?
For example, if your peak visits per hour is 200 visitors and the average visit duration is 6 minutes, the number of concurrent users that should be used to create 200 visits per hour is 20 concurrent users. Calculating the number of concurrent users is one of the many factors needed to properly setup a load test.
What does concurrent users mean in performance testing?
Concurrent users are the number of users engaged with the app or site at a given time. They’re all in the middle of some kind of session, but they are all doing different things. These are concurrent users.
What is concurrent users in Jmeter?
In both thread groups, set the Number of Threads. This is the number concurrent users you wish to simulate. In both thread groups, set the Loop Count. This number will determine how many times each thread is run, and therefore controls the length of the test.
When to use concurrent users in performance testing?
The word concurrent is used only for the events that occur over a period of time i.e. for a span of time. In the performance testing term, you would say ‘a period of time’ implies ‘test duration’. Hence the users which are running under a test plan; irrespective of the activities they are doing; are ‘Concurrent Users’. Figure 01: Concurrent Users.
Can a concurrent user be a simultaneous user?
The simultaneous user is a subset of the concurrent user. Simultaneous users can be concurrent users, but concurrent users cannot be simultaneous users. Generally, the number of concurrent users on an application is more than the number of simultaneous users.
How to calculate the number of concurrent users?
Only by knowing the test cases and additional numbers such as visits and page views per time unit can you a) define a number of concurrent users and b) check each number by means of calculation against the other numbers. Oh, and needless to say that 42 is always a good number of concurrent users…
How many concurrent users are needed to test 1, 800 visits?
If we want to test 1,800 visits again, we need 1,800 visits / (73.5 visits per hour per user) = 24.5 users, about 25. The number of page views stays the same since 1 visit equals 4 page views and the number of visits is constant. These 25 users need to complete their visits simultaneously and in parallel but still independent of one another.
