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): 2491.80Īverage measured interrupt to DPC latency (µs): 2.988339 Highest measured interrupt to process latency (µs): 2497.30Īverage measured interrupt to process latency (µs): 8.256721 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. OS version: Windows 10, 10.0, version 2009, build: 19042 (圆4)ĬPU: AuthenticAMD AMD FX(tm)-8350 Eight-Core Processor A lot of the advice I've found is more than five years old, so I thought I'd ask the experts on : is there anything else I can try here? Any help would be appreciated. I've updated everything I can, but I am using a previous version of my motherboard's BIOS because the most recent one was causing problems much worse that this. I've searched around online and all I can seem to find is advice to update drivers. I eleviated some latency by moving as many peripherals as I could to USB3.0, (EtronXHCI.sys) which seems to be less of a problem that USB2.0 but still ranks among the worst offenders. In the course of diagnosing this problem, I tried running LatencyMon and found that some drivers are hijacking the processor for a substantial amount of time. My Windows 10 has been having some trouble lately with games: lots of stuttering and general performance issues.
