  22. _________________________________________________________________________________________________________
  23. Reported CPU speed: 2994 MHz

  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): 598.112509
  34. Average measured interrupt to process latency (µs): 5.008508

  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.

  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.  
  88. Process with highest pagefault count: none
  89.  
  90. Total number of hard pagefaults 0
