  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. At least one detected problem appears to be network related. In case you are using a WLAN adapter, try disabling it to get better results. 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 0:06:18 (h:mm:ss) on all processors.

  22. _________________________________________________________________________________________________________
  23. Reported CPU speed: 1992 MHz
  24.  
  25. 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.

  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): 1816,674232
  34. Average measured interrupt to process latency (µs): 19,740292

  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): 2954,405622
  67. Driver with highest DPC routine execution time: ndis.sys - NDIS (Network Driver Interface Specification), Microsoft Corporation

  71.  
  72. Total time spent in DPCs (%) 0,859498
  73.  
  74. DPC count (execution time <250 µs): 684470

  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: msmpeng.exe
  90.  
  91. Total number of hard pagefaults 19942
  92. Hard pagefault count of hardest hit process: 3601
  93. Number of processes hit: 88
