Subject Re: How does the Response Time Graph and Thread Group works
Date Tue, 09 Apr 2013 16:23:46 GMT
Thanks for the reply, but I didn't understand yet.

If I have a Thread Group, with 4000 users, and this thread group have like
30 sampler http request, does it mean that the 4000 users will be divided
by the number of samplers?
