Related to this question: How can a Perfmon "% Processor Time" counter be over 100%?
I was manually observing processes in Task Manager when a user reported a problem and the Oracle process was using 80%-95% for a sustained period of time (5-15 minutes).
So I've been using perfmon for the last couple days to track that process and noticed it going OVER 100% for short periods, so it's apparently in perfmon it's the total over all the processors.
My question is that the 80-95% I was seeing in Task manager would really have been corresponding to 160-180% in perfmon, right?
(obviously factoring in that some processes may not be able to use all processors efficiently).
Task Manager was showing 80-95% CPU here:
Perf Monitor can spike above 100% on the line for a single process object:
