- CONCLUSION
- _________________________________________________________________________________________________________
- Your system seems to be having difficulty handling real-time audio and other tasks. You may experience drop outs, clicks or pops due to
- buffer underruns. One problem may be related to power management, disable CPU throttling settings in Control Panel and BIOS setup. Check
- for BIOS updates.
- LatencyMon has been analyzing your system for 11:27:19 (h:mm:ss) on all processors.

- CPU SPEED
- _________________________________________________________________________________________________________
- Reported CPU speed (WMI): 3501 MHz
- Reported CPU speed (registry): 3493 MHz
- Note: reported execution times may be calculated based on a fixed reported CPU speed. Disable variable speed settings like Intel Speed
- Step and AMD Cool N Quiet in the BIOS setup for more accurate results.

- 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): 1504.20
- Average measured interrupt to process latency (µs): 6.485503
- Highest measured interrupt to DPC latency (µs): 1465.20
- Average measured interrupt to DPC latency (µs): 0.951080
- _________________________________________________________________________________________________________
- 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): 10.591182
- Driver with highest ISR routine execution time: Wdf01000.sys - Kernel Mode Driver Framework Runtime, Microsoft Corporation
- Highest reported total ISR routine time (%): 0.000030
- Driver with highest ISR total time: Wdf01000.sys - Kernel Mode Driver Framework Runtime, Microsoft Corporation
- Total time spent in ISRs (%) 0.000030
- ISR count (execution time <250 µs): 609703
- 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): 591.903808
- Driver with highest DPC routine execution time: ntoskrnl.exe - NT Kernel & System, Microsoft Corporation

- DPC count (execution time 500-10000 µs): 98
- 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: nvcontainer.exe
- Total number of hard pagefaults 32094
- Hard pagefault count of hardest hit process: 15498
- Number of processes hit: 63
