Interrupt service routines are routines installed by the OS and device drivers that execute in response to a hardware Highest measured interrupt to DPC latency (µs): 135.60Īverage measured interrupt to DPC latency (µs): 1.283203 Highest measured interrupt to process latency (µs): 519.20Īverage measured interrupt to process latency (µs): 5.162873 This includes the scheduling and execution of aĭPC routine, the signaling of an event and the waking up of a usermode thread from an idle wait state in response to that Request from the moment the interrupt service routine started execution. The interrupt to process latency reflects the measured interval that a usermode process needed to respond to a hardware MEASURED INTERRUPT TO USER PROCESS LATENCIES 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.
