What method do you use when you want to get performance data about specific code paths?
Well, I have two code snippets. In pseudocode they are looking like (it's a simplified version, I'm using QueryPerformanceFrequency actually):
Timer timer = new Timer
timer.Start
timer.Stop
show elapsed time
A bit of hot-keys kung fu, and I can say how much time this piece of code stole from my CPU.
