CONCLUSION
_________________________________________________________________________________________________________
Your system appears to be having trouble handling real-time audio and other tasks. You are likely to experience buffer underruns appearing as drop outs, clicks or pops. 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 0:00:59 (h:mm:ss) on all processors.

SYSTEM INFORMATION
_________________________________________________________________________________________________________
Computer name: DESKTOP-VBNDHEJ
OS version: Windows 10 , 10.0, build: 17134 (x64)
Hardware: H270-Gaming 3, Gigabyte Technology Co., Ltd.
CPU: GenuineIntel Intel(R) Core(TM) i5-7600 CPU @ 3.50GHz
Logical processors: 4
Processor groups: 1
RAM: 16338 MB total
_________________________________________________________________________________________________________
CPU SPEED
_________________________________________________________________________________________________________
Reported CPU speed: 3504 MHz
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.
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.

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): 100832,963897
Average measured interrupt to process latency (µs): 9,696715
Highest measured interrupt to DPC latency (µs): 100772,178544
Average measured interrupt to DPC latency (µs): 4,710968
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.

Total time spent in DPCs (%) 0,928875
DPC count (execution time <250 µs): 130887
DPC count (execution time 250-500 µs): 0
DPC count (execution time 500-999 µs): 4
DPC count (execution time 1000-1999 µs): 0
DPC count (execution time 2000-3999 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: avastsvc.exe
Total number of hard pagefaults 2
Hard pagefault count of hardest hit process: 1
Number of processes hit: 2
