  2. CONCLUSION
  3. _________________________________________________________________________________________________________
  4. Your system appears to be having trouble handling real-time audio and other tasks. You are likely to experience buffer underruns appearing as drop outs, clicks or pops. One or more DPC routines that belong to a driver running in your system appear to be executing for too long. Also one or more ISR 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 0:17:13 (h:mm:ss) on all processors.

  25. Reported CPU speed (WMI): 3686 MHz
  26. Reported CPU speed (registry): 3686 MHz
  27.  
  28. 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.

  32. MEASURED INTERRUPT TO USER PROCESS LATENCIES
  33. _________________________________________________________________________________________________________
  34. 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.
  35.  
  36. Highest measured interrupt to process latency (µs): 21141.60
  37. Average measured interrupt to process latency (µs): 4.546017

  44. REPORTED ISRs
  45. _________________________________________________________________________________________________________

  65. REPORTED DPCs
  66. _________________________________________________________________________________________________________
  67. 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.
  68.  
  69. Highest DPC routine execution time (µs): 17039.510038
  70. Driver with highest DPC routine execution time: Wdf01000.sys - Kernel Mode Driver Framework Runtime, Microsoft Corporation

  85. _________________________________________________________________________________________________________
  86. REPORTED HARD PAGEFAULTS
  87. _________________________________________________________________________________________________________
  88. 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.
  89.  
  90. 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.
  91.  
  92. Process with highest pagefault count: microsoft.photos.exe
  93.  
  94. Total number of hard pagefaults 12607
  95. Hard pagefault count of hardest hit process: 1743
  96. Number of processes hit: 45
