How to calculate the number of concurrent users?

How to calculate the number of concurrent users?

Concurrent users = Peak Hourly Visits x Average Visit Duration (in minutes)/60 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.

When to use concurrent function in an app?

In the OnStart property of your app, use Concurrent to improve performance when the app loads data. When data calls don’t start until the previous calls finish, the app must wait for the sum of all request times. If data calls start at the same time, the app needs to wait only for the longest request time.

Can you take dependencies outside the concurrent function?

Formulas within the Concurrent function shouldn’t contain dependencies on other formulas within the same Concurrent function, and Power Apps shows an error if you try. From within, you can safely take dependencies on formulas outside the Concurrent function because they will complete before the Concurrent function starts.

How are multiple formulas evaluated in concurrent function?

The Concurrent function evaluates multiple formulas at the same time. Normally, multiple formulas are evaluated by chaining them together with the ; (or ;;) operator, which evaluates each sequentially in order. When the app performs operations concurrently, users wait less for the same result.

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 to calculate the number of virtual users required while?

Hence using above formula: Number of virtual users = 10 * 10 * 3600 / 600 = 600 Hence the above formula gives a user count of 600 users. However a noticeable point is in an hour a user runs for only 10 mins and is inactive for most of the time.

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.

How many page views per hour with 100 concurrent users?

In the worst case (note that 1 page view takes 1 sec on the server side), however, this would amount to 100 * 3,600 sec = 36,000 page views per hour. Since the requirement of 100 concurrent users is actually never bound to a certain period, you therefore have to assume that these users could potentially click at any time.
