I'm going to do Load/Performance testing for Web API services using JMeter.
I know how to create a test plan but I don't know how to identify the user virtual count for the Mobile/Web. Can we increase the users count by 50,100,250,1000.., is it right
Which one is best to do the load testing whether create a test plan separately or recording the script? I can do this both, but I want to know which one is efficient to do load testing.
