PerfMon CPU Usage not same as Task Manager reading
-
Hi, I am trying to create a CPU Usage monitoring application. I am using PerformanceMonitor to do it. However as I was observing the data from Task Manager's CPU Usage column (Process Tab) and Performance Monitor (Process - % Processor Time) readings, they don't seem to coincide at all (Not even close). I tried to change the Performance Monitors sampling interval, but I can't seem to make the 2 coincide. Does anyone, know why the readings are different? Thanks. :)

Ignore task manager, it's inaccurate. perf mon is the way to go. http://windowsitpro.com/article/articleid/81667/jsi-tip-8404-cpu-usage-in-task-manager-may-be-incorrect.html[^]
