Why % Processor Time of W3WP is higher than % Processor Time of the whole processor?

Question

I run perfmon on one of the Production Server Machines. My aim was to monitor the Processor load.

This is the result: http://img443.imageshack.us/img443/3765/lf6.gif

Could you please tell me why "% Processor Time" of the process W3WP is higher than every other "% Processor Time" of the single processors and of the "% Processor Time" total?
Any suggestion?

Answer 1

The % Processor Time of a process is calculated on a base line of (100 * number of logical processors).

The Total % Processor Time is not.

Nevertheless if % Processor Time of a process is greater than (100 * number of logical CPUS) it means that the process is using the processing units to more of their actual capacity.
