SYMPTOMS
Windows NT 4.0 Performance Monitor (Perfmon4.exe) Help states that the Processor - %DPC Time is &quot;a component of % Privileged Time because DPCs are executed in privileged mode. They are counted separately and are not a component of the interrupt counters.&quot; This implies that the %Privilege Time does not include %DPC Time.



MORE INFORMATION
The Performance Monitor Processor Counter explanation may be difficult to interpret. Note that %DPC time is included with %Privileged Time and is also counted separately. The is also true for %Interrupt Time. %Processor Time equals %User time plus %Privileged Time.
