  2. CONCLUSION
  3. _________________________________________________________________________________________________________
  4. 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 or more DPC routines that belong to a driver running in your system appear to be executing for too long. One problem may be related to power management, disable CPU throttling settings in Control Panel and BIOS setup. Check for BIOS updates.
  5. LatencyMon has been analyzing your system for 0:04:44 (h:mm:ss) on all processors.

  29. MEASURED INTERRUPT TO USER PROCESS LATENCIES
  30. _________________________________________________________________________________________________________
  31. 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.
  32.  
  33. Highest measured interrupt to process latency (µs): 323.10
  34. Average measured interrupt to process latency (µs): 5.066033

  41. REPORTED ISRs
  42. _________________________________________________________________________________________________________
  43. Interrupt service routines are routines installed by the OS and device drivers that execute in response to a hardware interrupt signal.

  62. REPORTED DPCs
  63. _________________________________________________________________________________________________________
  64. 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.
  65.  
  66. Highest DPC routine execution time (µs): 1826.450
  67. Driver with highest DPC routine execution time: nvlddmkm.sys - NVIDIA Windows Kernel Mode Driver, Version 471.68 , NVIDIA Corporation

  83. REPORTED HARD PAGEFAULTS
  84. _________________________________________________________________________________________________________
  85. 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.
  86.  
  87. 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.
  88.  
  89. Process with highest pagefault count: nvcontainer.exe
  90.  
  91. Total number of hard pagefaults 2685
  92. Hard pagefault count of hardest hit process: 1802
  93. Number of processes hit: 52
