Ants profile shows 150 percent of CPU usage

Question

I am using Red-gate Ants profiler. When I profile my application it shows lot of spikes and show that the CPU usage is 150%.

How is that possible the usage to go beyond 100% ??

Additionally I would really appreciate if anyone can tell me how to troubleshoot and pin point the issues causing this huge usage.

Answer 1

From the Red-gate Ants FAQ:

CPU usage exceeds 100%

ANTS Performance Profiler analyzes CPU usage per core. So, on a quad-core machine an application taking all time on all cores would be shown as taking 400% of CPU time.
