When doing Performance work, the first place you always need to start with is knowing your baseline.
If you don’t know your baseline, you will not know what tools to build, what tests to run, and where to move forward to.
How do you hit your baseline?
You send it traffic, then you up, measure it, if it’s still working, up it some more. You keep upping it until it falls over and then you go to the test before where things worked – that’s your baseline.
Without a proper baseline, all you are doing is throwing darts in a dark room hoping one of them hits the target.
