MEASURED INTERRUPT TO USER PROCESS LATENCIES
_________________________________________________________________________________________________________
The interrupt to process latency reflects the measured interval that a usermode process needed to respond to a hardware request from the moment the interrupt service routine started execution. This includes the scheduling and execution of a DPC routine, the signaling of an event and the waking up of a usermode thread from an idle wait state in response to that event.
Highest measured interrupt to process latency (µs): 180.0
Average measured interrupt to process latency (µs): 10.432969
Highest measured interrupt to DPC latency (µs): 138.70
Average measured interrupt to DPC latency (µs): 3.117470

REPORTED DPCs
_________________________________________________________________________________________________________
DPC routines are part of the interrupt servicing dispatch mechanism and disable the possibility for a process to utilize the CPU while it is interrupted until the DPC has finished execution.

Total time spent in DPCs (%) 0.240996
DPC count (execution time <250 µs): 25569
DPC count (execution time 250-500 µs): 0
DPC count (execution time 500-10000 µs): 0
DPC count (execution time 1000-2000 µs): 0

REPORTED HARD PAGEFAULTS
_________________________________________________________________________________________________________
Hard pagefaults are events that get triggered by making use of virtual memory that is not resident in RAM but backed by a memory mapped file on disk. The process of resolving the hard pagefault requires reading in the memory from disk while the process is interrupted and blocked from execution.
NOTE: some processes were hit by hard pagefaults. If these were programs producing audio, they are likely to interrupt the audio stream resulting in dropouts, clicks and pops. Check the Processes tab to see which programs were hit.
Process with highest pagefault count: googledrivefs.exe
Total number of hard pagefaults 1274
Hard pagefault count of hardest hit process: 1156
Number of processes hit: 20
