work to do (any ready SRB, interrupted ready task, asynchronous exit
routine, or TCB is on the dispatching queue), then it looks for the
first address space having a unit of work on the dispatching queue
that is not already using another processor. Then the number of samples
is incremented by one for the address space having the first dispatchable
unit of work according to the dispatcher sequence search order. The
processor running Monitor III is not counted as a processor in use
if there is no other ready work to do.The percentage of delay caused by the third most impacting job to the job waiting to use the processor.

for the processor. Hiperspace Paging Wait Percentage (RMF metric) Percentage of time the job is waiting for Hiperspace Page.
