Yep that's fine, they're just two different calculations :) ]]> RE: CPU indicator not matching Task Manager https://www.traystatus.com/Discussions/View/cpu-indicator-not-matching-task-manager/?ID=cf61cfd3-c933-435c-baf9-5589c6c96760#3 Thu, 24 Mar 2022 19:54:21 GMT Binary Fortress Software https://www.traystatus.com/Discussions/View/cpu-indicator-not-matching-task-manager/?ID=cf61cfd3-c933-435c-baf9-5589c6c96760#3 TrayStatus So does that mean that I should not worry about the difference, and should "trust" the Task Manager instead?

Hi Fred,

The CPU calculations in task manager are internal calculations done by Windows, that aren't exposed anywhere for us to use. We use the "% Processor Time" counter found in Performance Monitor.

There's an article that explains it further here if you're interested: https://social.technet.microsoft.com/wiki/contents/articles/12984.understanding-processor-processor-time-and-process-processor-time.aspx

Thanks!

Regularly showing 20% less. The RAM indicator appears to have the same readings as Task Manager.
