The indication from the CPU indicator in Tray Status shows much less CPU usage than the Windows Task Manager. Regularly showing 20% less. The RAM indicator appears to have the same readings as Task Manager.

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!

So does that mean that I should not worry about the difference, and should "trust" the Task Manager instead?

Hi Fred,

Yep that's fine, they're just two different calculations
