Highest ISR routine execution time (µs): 54.138333ĭriver with highest ISR routine execution time: Wdf01000.sys - Kernel Mode Driver Framework Runtime, 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): 238.10Īverage measured interrupt to DPC latency (µs): 1.566288 Highest measured interrupt to process latency (µs): 298.30Īverage measured interrupt to process latency (µs): 6.275653 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.
