An average counter that shows the average number of operations completed in one second. When a counter of this type samples the data, each sampling interrupt returns one or zero. The counter data is the number of ones that were sampled. It measures time in units of ticks of the system performance timer.
Formula: (N – N ) / ((D – D ) / 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 F represents the number of ticks that elapse in one second. F is factored into the equation so that the result can be displayed in seconds.
