![]() ![]() Highest DPC routine execution time (µs): 15396,468525ĭriver with highest DPC routine execution time: Wdf01000.sys - Aparat wykonawczy struktury sterowników trybu jądra, Microsoft Corporation Highest reported total ISR routine time (%): 0,013849ĭriver with highest ISR total time: HDAudBus.sys - High Definition Audio Bus Driver, 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. Highest ISR routine execution time (µs): 75,458503ĭriver with highest ISR routine execution time: HDAudBus.sys - High Definition Audio Bus Driver, Microsoft Corporation 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): 15274,50Īverage measured interrupt to DPC latency (µs): 2,394802 Highest measured interrupt to process latency (µs): 15279,50Īverage measured interrupt to process latency (µs): 6,492128 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. MEASURED INTERRUPT TO USER PROCESS LATENCIES 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: B85M-D3H-A, Gigabyte Technology Co., Ltd.ĬPU: GenuineIntel Intel(R) Core(TM) i5-4570 CPU 3.20GHz LatencyMon has been analyzing your system for 0:30:02 (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.
