SYSTEM INFORMATION
_________________________________________________________________________________________________________
Computer name: mycomputer
OS version: Windows 10, 10.0, version 1909, build: 18363 (x64)
Hardware: Z270-HD3P, Gigabyte Technology Co., Ltd.
CPU: GenuineIntel Intel(R) Core(TM) i7-7700K CPU @ 4.20GHz

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): 359,40
Average measured interrupt to process latency (µs): 5,592411
Highest measured interrupt to DPC latency (µs): 349,80
Average measured interrupt to DPC latency (µs): 2,145748

REPORTED ISRs
_________________________________________________________________________________________________________
Interrupt service routines are routines installed by the OS and device drivers that execute in response to a hardware interrupt signal.
Highest ISR routine execution time (µs): 31,566190
Driver with highest ISR routine execution time: Wdf01000.sys - Kernel Mode Driver Framework Runtime, Microsoft Corporation
Highest reported total ISR routine time (%): 0,007726
Driver with highest ISR total time: Wdf01000.sys - Kernel Mode Driver Framework Runtime, Microsoft Corporation
Total time spent in ISRs (%) 0,009192
ISR count (execution time <250 µs): 108871
ISR count (execution time 250-500 µs): 0
ISR count (execution time 500-1000 µs): 0
ISR count (execution time 1000-2000 µs): 0
ISR count (execution time 2000-4000 µs): 0
ISR count (execution time >=4000 µs): 0
_________________________________________________________________________________________________________
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.
Highest DPC routine execution time (µs): 347,833333
Driver with highest DPC routine execution time: ntoskrnl.exe - NT Kernel & System, Microsoft Corporation
Highest reported total DPC routine time (%): 0,273559
Driver with highest DPC total execution time: Wdf01000.sys - Kernel Mode Driver Framework Runtime, Microsoft Corporation
Total time spent in DPCs (%) 0,388305
DPC count (execution time <250 µs): 775370
DPC count (execution time 250-500 µs): 0
DPC count (execution time 500-10000 µs): 24
DPC count (execution time 1000-2000 µs): 0
DPC count (execution time 2000-4000 µs): 0
DPC count (execution time >=4000 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: svchost.exe
Total number of hard pagefaults 11
Hard pagefault count of hardest hit process: 6
Number of processes hit: 2
