DPC Time
- % DPC Time is the percentage of elapsed time that the Processor spent in Deferred Procedure Calls. When a hardware device interrupts the Processor, the Interrupt Handler may elect to execute the majority of its work in a DPC. DPC's run at lower priority than Interrupts, and so permit Interrupts to occur while DPC's being execute. Deferred Procedure Calls are executed in Privileged Mode, so this is a component of Processor: % Privileged Time. This counter can help determine the source of excessive time being spent in Privileged Mode.
