PERF_PRECISION_OBJECT_TIMER

Description This counter type shows a value that consists of two counter values: the count of the elapsed time of the event being monitored, and the frequency specified in the PerfFreq field of the object header.
This counter type differs from other counter timers in that the clock tick value accompanies the counter value so as to eliminate any possible difference due to latency from the function call. Precision counter types are used when standard system timers are not precise enough for accurate readings.
Generic type Percentage
Formula NX – N0 / D1 – D0 where the numerator (N) represents the counter value and the denominator (D) is the value of the private timer.
Average NX – N0 / D1 – D0
Example There are no counters of this type installed with Windows 2000.
