Description

This counter type shows the average number of operations completed in one second. It measures time in units of ticks of the system performance timer. The variable F represents the number of ticks that occur in one second. The value of F is factored into the equation so that the result is displayed in seconds.

Generic type

Formula

(N1 - N0) / ((D1 - D0) / F), where the numerator (N) represents the number of operations completed, the denominator (D) represents elapsed time in units of ticks of the system performance timer, and the variable F represents the number of ticks that elapse in one second.

Average

(Nx - N0) / ((Dx - D0) / F)
