What's the maximum number of virtual users you can assign to a test?

The number of VUs that can be created during the test by each WAPT Pro load agent depends on several parameters including the hardware of agents systems, network capability and the tested server itself. For example, if typical response time is very short, the agent will have less time for preparing and sending subsequent requests. So, in this case each agent will create less simultaneous VUs. However this will also result in more user sessions executed during a time frame. What I am trying to say is that it is easier to create many simultaneous users for a slow site then for a fast one. Also, maximum number of concurrent VUs depends on the profiles that you use and the content of server responses. For example, a load agent will work more efficiently if typical server response is a short message, then if it is a 100kb HTML text.

Overall the average number is about 1000 – 2000 VUs per load agent. By the way, if you want, you can purchase additional load agents separately, if you see that your current configuration is insufficient.

WAPT works identically to WAPT Pro with a single load agent running on the same system.
