Hello, I am CONSTANTLY seeing a process use between 179-1058% average cpu per instance, the CPU Usage Total is between 11-66%. I would think the process average per instance would be far less than the total % :-) Whats going on?

Hello there,

Please take a look at this thread for an explanation.

So for other people landing on this post from a search engine...... if you have 4 processors and a process is using 100% of all 4 processors the per instance percent would be 400% In my case i have 20 processors so I could see usage as high as 2000%

kind of weird... I think (my opinion) it should be a number similar to the TOTAL but per instance. So if my total cpu usage was 30% and i had three instances running, i would rather the per instance percent show 10% But hey... It works.. :-)

Yes, it's "the blessing and the curse" of multithreaded applications as also the aforementioned post explained (one process, but several threads that you don't see in Taskmanager deriving from it, performing different operations utilizing several cores) :-)

Kind regards.
