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. Highest reported total DPC routine time (%): 0.054523ĭriver with highest DPC total execution time: storport.sys - Microsoft Storage Port Driver, Microsoft Corporation Highest DPC routine execution time (µs): 100364.573954ĭriver with highest DPC routine execution time: storport.sys - Microsoft Storage Port Driver, Microsoft Corporation Highest reported total ISR routine time (%): 0.054056ĭriver with highest ISR total time: dxgkrnl.sys - DirectX Graphics Kernel, Microsoft CorporationĭPC 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.

Interrupt service routines are routines installed by the OS and device drivers that execute in response to a hardware interrupt signal. Highest measured interrupt to DPC latency (µs): 73.625215Īverage measured interrupt to DPC latency (µs): 1.489638 Highest measured interrupt to process latency (µs): 130.352840Īverage measured interrupt to process latency (µs): 3.767530 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. 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.

It is suggested that you run a utility which reports your actual CPU frequency and temperature. Your CPUs may be throttled back due to variable speed settings and thermal issues. WARNING: the CPU speed that was measured is only a fraction of the CPU speed reported.

Disable variable speed settings like Intel Speed Step and AMD Cool N Quiet in the BIOS setup for more accurate results. Note: reported execution times may be calculated based on a fixed reported CPU speed. Hardware: ASUSTeK COMPUTER INC., CROSSHAIR VI HEROĬPU: AuthenticAMD AMD Ryzen 7 1700X Eight-Core Processor LatencyMon has been analyzing your system for 0:00:23 (h:mm:ss) on all processors. One problem may be related to power management, disable CPU throttling settings in Control Panel and BIOS setup. One or more DPC routines that belong to a driver running in your system appear to be executing for too long. You are likely to experience buffer underruns appearing as drop outs, clicks or pops. Your system appears to be having trouble handling real-time audio and other tasks.
