CPU consumption of my process

I would like to use Performance Monitor to check the CPU consumption of my process. Right now I am working on a MultiCore machine.

If I have a look at my process in TASK MANAGER I see that my process consumes 20% of CPU. If I start performance monitor, I select Process->->% Processor Time I see values peaking up and over 100%. Do you know why and how to get the real measure?

I also looked at the CPU consumption for all of my 4 cores, but I don't know ex开发者_StackOverflow社区actly how to attribute consumption to my process.

If you can suggest a link or url about how to read CPU usage I would really appreciate! Thanks a lot! AFG

Try Process Explorer from Sysinternals. Very useful.

This article explains what you are seeing.

Basically Task Manager averages the cores together, and Performance Monitor sums up the the Process's time on each core. So, % Processor Time on a system with 4 cores could go up to 400. N * 100 = MaxValue; Where N is the number of cores/processors in the system.
