  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  0:39:20  (h:mm:ss) on all processors.

  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.

  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.
