Processor DPC time is the time that a single processor spent receiving and servicing deferred procedure
calls (DPCs). DPCs are interrupts that run at a lower priority than standard interrupts. % DPC Time is a
component of % Privileged Time because DPCs are executed in privileged mode. If a high % DPC Time is
sustained, there may be a processor bottleneck or an application or hardware related issue that can
significantly diminish overall system performance.
