To answer your question directly, calculation for "Average concurrent user" will not be equal to "concurrent user" because one of them is calculating for average value while the other is absolute value. For more information, see Specify the number of virtual users with load patterns in a load test scenario. Run the script again with ten virtual users. Compute the number of Virtual Users required for your Performance Test. Fill one of the two tables below to get the required number of virtual users. Estimate the number of virtual users you need to simulate load on your website. You can choose from the three available patterns: step pattern, constant and goal based. What should be the peak load? "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 … 3. 6. This is a user provided value based on actual requirements of the load test. 5. The main purpose of VUsers is to simulate the live environment. A load pattern specifies the number of virtual users active during a load test, and the rate at which new users are added. What should be the concurrent virtual users to load? More importantly, your posted question appears to be related to general load testing against a website. 4. We cannot give number of VUsers blindly which will not return intuitive result for analysis. Record the amount of memory and CPU percentage used by the different processes. Number of Virtual Users: This is the number of virtual users that will be used to run that user group. How to design your load test. The good thing is that LoadView can take the complexity and worry out of load testing. Since the test is one hour long (probably representing the peak hour in the day) and the script only takes on average 6 minutes (including think time) to execute, I can re-use that vuser to simulate the load of up to 10 normal users over the hour duration. It shows your scenario of 30K users for 60 minutes costing $712. Calculating the number of virtual users for browser driven load testing There are no fixed guidelines on this type of testing because each virtual user has to run the browser application (BrowserApplication.exe) and the full application gets rendered in the browser application so it is also dependent on the size of the application. tl;dr — This post is about using Google Analytics to determine how many concurrent users to specify in your load tests. 25, 100, 500, 1000. How to calculate number of virtual users (VUsers) for load/stress testing? Multiply those numbers by the desired number of virtual users. However, if you calculate the average concurrent sessions for just Nov. 25, you get 1.05 — … Run that sample as a single-user load test in order to get baseline resource utilization. The total may or may not mean much but it does provide the total TPM at a glance. ... = .08 average concurrent users in November. This provides a baseline for a single virtual user. Typically, you'll be working with a specific peak load over a one hour period that you are trying to simulate (e.g. Given the free 20K virtual user minutes per month (VUM), breaking this down the cost is: (30,000 VUM x 60 Minutes - 20,000 Free Minutes) x $0.0004 = (1.8 Million VUM - 20K VUM) x $0.0004 = LoadView steps you through the process and takes out the hassle of having to manage load injectors or virtual machines. The Total in last row gives the total load (in TPM) for this whole scenario. The Azure Pricing Calculator has a slider for calculating the load test cost.
