How do you determine concurrent user count for load testing?
I’m working on a load test for a SaaS application and I’m trying to figure out how to turn expected traffic into a realistic number of concurrent users.
The customer has a large user base, but obviously that doesn’t mean everyone will be using the application at the same time. I’m not sure whether I should be looking at average traffic, peak traffic, active sessions, or some combination of those when setting the test target.
I’ve gotten a few different answers so far, so I’m curious how other teams usually approach this. Is there a standard way to estimate concurrent users when you don’t have much historical data to work with?
