What is setUp thread group in JMeter?

How many threads can be executed at a time in JMeter?
JMeter allows you to run multiple processes in the same box, and it’s usually pretty reliable generating up to 200 threads per JMeter instance. If you need more than that, I’d recommend using multiple JMeter instances. A modern machine with some tweaking can easily generate 500 to 1000 threads.

What should the standard deviation be on a JMeter?
Standard Deviation: should be low. A high deviation indicates discrepancies in responses times, which translates to response time spikes. See, it’s pretty easy! Most of the figures should be as low as possible. However, depending on the context, your boss may provide you with expected responses times under a given load.
