During performance testing, I found that the values of Process(w3wp)\% Processor Time are greater than 100. Some values are
237.1436486
312.5338052
341.2373994
264.4097661
191.6237736
I thought this value represents the CPU usage by w3wp process. I don’t understand why the value is greater than 100%.
If you have multiple cores it can go over 100, it’s the sum of the processor usage for each processor (core, or virtual core) so over 100 is normal (
100*numberOfCoresis the nax).Use the
Process(w3wp_Total)version of the counter if you want the overall CPU %, this caps out at 100.
