CPU SPEED
_________________________________________________________________________________________________________
Reported CPU speed: 2809.0 MHz
Measured CPU speed: 4244.0 MHz (approx.)
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.

MEASURED INTERRUPT TO USER PROCESS LATENCIES
_________________________________________________________________________________________________________
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.
Highest measured interrupt to process latency (µs): 221.245389
Average measured interrupt to process latency (µs): 3.963049
Highest measured interrupt to DPC latency (µs): 174.226188
Average measured interrupt to DPC latency (µs): 0.958647

MEASURED SMI, IPI AND CPU STALLS
_________________________________________________________________________________________________________
The SMI, IPI and CPU stalls value represents the highest measured interval that a CPU did not respond while having its maskable interrupts disabled.
Highest measured SMI or CPU stall (µs) 17.860007

REPORTED DPCs
_________________________________________________________________________________________________________
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.

REPORTED HARD PAGEFAULTS
_________________________________________________________________________________________________________
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.
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.
Process with highest pagefault count: msmpeng.exe
Total number of hard pagefaults 3670
Hard pagefault count of hardest hit process: 631
Highest hard pagefault resolution time (µs): 951914.945888
Total time spent in hard pagefaults (%): 0.910484
Number of processes hit: 25
