CPU SPEED
_________________________________________________________________________________________________________
Reported CPU speed:                                   2798,0 MHz
Measured CPU speed:                                   3634,0 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):   544,926221
Average measured interrupt to process latency (µs):   4,786004

Highest measured interrupt to DPC latency (µs):       543,828317
Average measured interrupt to DPC latency (µs):       1,203119


_________________________________________________________________________________________________________
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)                3,293711

 REPORTED ISRs
_________________________________________________________________________________________________________

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.


Process with highest pagefault count:                 none

Total number of hard pagefaults                       0
Hard pagefault count of hardest hit process:          0
Highest hard pagefault resolution time (µs):          0,0
Total time spent in hard pagefaults (%):              0,0
Number of processes hit:                              0
