On my system (Windows 7), it seems that Process Explorer is reporting the wrong CPU usage:
- When Firefox is running, I constantly get 30%+
- When I kill Firefox, I still get about the same CPU usage
- If I sort by CPU time, Process Explorer itself is taking between 18% and 22%
- Task Manager reports < 10% (which is still a lot while doing nothing)
… all of this while doing nothing special, just having those apps open.
CPU: Intel Core2 Duo P8600 2.4 GHz
Any ideas or ways to investigate this problem?
