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 0:02:35 (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): 77153,90
Average measured interrupt to process latency (µs): 272,304914
Highest measured interrupt to DPC latency (µs): 77137,60
Average measured interrupt to DPC latency (µs): 259,661517

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: systemsettings.exe
Total number of hard pagefaults 849
Hard pagefault count of hardest hit process: 524
Number of processes hit: 25
