In such cases, total users could number in the thousands. © 2008-2021 LoadStorm, LLC. Each office has 2,000 employees. Change ), USE WINDOWS SERVER TO PERFORM A SIMPLE MULTI-USER LOAD TEST WITH APPLOADER ». For our example, we’ll say 1,000 in each office. For example, if you successfully run a 100-user test, then see a value of 50 for Max Users , that means of the your 100 users that ran, 50 of them ran simultaneously. Anyone who works in an office knows that 100% of the employees are rarely in the office at the same time, let alone sitting at their desks hammering away at an application.

So for me to guess the concurrent users on a peak hr, am doing below math. 250 query logged in users x 2 offices = 500 I have to come up with a concurrent user base for my app where there would be 3420 phone stores in total. Here’s the math: The total simulated users will generally be much higher than concurrent users, but the actual count depends on lots of other factors such as the number of pages in the script, think times, etc. I have searched extensively to try and get some figures on how many concurrent users SharePoint can typically handle but havent had much luck.

The other 250 query users login only when they need to do a query, then logout. Thus Average Concurrent User comes around 20. That would assume that 100% of all potential users are logged in at the same time. The LoadStorm test parameters simulate “concurrent” users not total users.
