Graph Information

% Priority Time is the percentage of elapsed time that the processor spends executing threads that are not low priority. It is calculated by measuring the percentage of time that the processor spends executing low priority threads or the idle thread and then subtracting that value from 100%. (Each processor has an idle thread to which time is accumulated when no other threads are ready to run). This counter displays the average percentage of busy time observed during the sample interval excluding low priority background work. It should be noted that the accounting calculation of whether the processor is idle is performed at an internal sampling interval of the system clock tick. % Priority Time can therefore underestimate the processor utilization as the processor may be spending a lot of time servicing threads between the system clock sampling interval. Workload based timer applications are one example of applications which are more likely to be measured inaccurately as timers are signaled just after the sample is taken.
