Recently , I use WPT to diagnose system performance, but i have a problem about WPT:
I use WPR to record for 15 seconds, then stop and open the result etl file with windows performance analyzer, in "DPC and ISR usage by module,stack" view, the Count of function halpTimerClockInterrupt is "2", what i know is in normal situations, it should be 15s * 64= 960 ( because timer resolution is 15.625ms).
Does any one seen this before? Thanks!
