Olá, eu esses dias tive um downgade pesado no meu computador após ficar bom tempo no conserto, e com poucos dias usando eu acabei descobrindo enquanto eu jogava ou fazia alguma outra coisa, que meu pc estava dando algumas engasgadas chatas e voltava como se nada tivesse acontecido, e notei também que as músicas que estava ouvindo também estava engasgando!
É questão de milésimos de segundos que congela e depois volta, e como isso estava me irritando, eu fui atrás de resolver, e acabei me deparando com latencymon, então acabei fazendo vários teste, e esse aqui foi o ultimo teste que eu fiz.
Aqui para baixo foi o que acabou saindo no teste que eu fiz agora, literalmente fiquei fazendo nada por 11 minutos.
CONCLUSION
Your system seems to be having difficulty handling real-time audio and other tasks. You may experience drop outs, clicks or pops due to buffer underruns. 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.
LatencyMon has been analyzing your system for 0:12:23 (h:mm:ss) on all processors.

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): 819,80
Average measured interrupt to process latency (µs): 9,250460
Highest measured interrupt to DPC latency (µs): 814,60
Average measured interrupt to DPC latency (µs): 5,255143
REPORTED ISRs
Interrupt service routines are routines installed by the OS and device drivers that execute in response to a hardware interrupt signal.

Total time spent in ISRs (%) 0,013427
ISR count (execution time <250 µs): 115718
ISR count (execution time 250-500 µs): 0

ISR count (execution time 2000-4000 µs): 0
ISR count (execution time >=4000 µs): 0
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.

DPC count (execution time 2000-4000 µs): 0
DPC count (execution time >=4000 µs): 0
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 4277
Hard pagefault count of hardest hit process: 1074
Number of processes hit: 84
