PID Rate D

I have a question about PID Rate D parameter. How it affect flight performance?
What happens on too low and too high D and how to find normal value for my frame?

D is the "derivative"-correction, it basecally does two things: counteracting fast disturbances and dampening mainly P (avoiding overshoots of corrections).

Hope that helps,
