In a sample web application running on a 2 CPU machine, I have the following
Performance Counter values:

Average % Processor Time - Total = 67%
Average % Processor Time - aspnet_wp = 109%
Average % Time in GC - aspnet_wp = 26%

I know that the second value (109) is out of 200 because there are two CPUs.
What is the 26% telling me? Is that 26% of the 109% or 26% of the 67%.

Mark,

The value is time based, so the 26% means that 26% of the time since the
last GC was spent in the current GC. Thus, the answer is 26% of the 67%.

Hope this helps.
