  20. CPU SPEED
  21. _________________________________________________________________________________________________________
  22. Reported CPU speed: 3591 MHz
  23. Measured CPU speed: 1 MHz (approx.)
  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.
  26.  
  27. WARNING: the CPU speed that was measured is only a fraction of the CPU speed reported. Your CPUs may be throttled back due to variable speed settings and thermal issues. It is suggested that you run a utility which reports your actual CPU frequency and temperature.

  32. MEASURED INTERRUPT TO DPC LATENCIES
  33. _________________________________________________________________________________________________________
  34. The interrupt to DPC latency reflects the measured interval in which a DPC could execute in response to a hardware request from the moment the interrupt service routine started execution.
  35.  
  36. Highest measured interrupt to DPC latency (µs): 564.496908
  37. Average measured interrupt to DPC latency (µs): 1.788503

  39.  
  40. _________________________________________________________________________________________________________
  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.
  44.

  61. _________________________________________________________________________________________________________
  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.

  82. _________________________________________________________________________________________________________
  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: mspaint.exe
  90.  
  91. Total number of hard pagefaults 2042
  92. Hard pagefault count of hardest hit process: 692
  93. Highest hard pagefault resolution time (µs): 76557.491228
  94. Total time spent in hard pagefaults (%): 0.001155
  95. Number of processes hit: 15
