Running Background Apps on Efficiency Cores

St. Clair Software:

As you can see in the image on the left, App Tamer now displays graphs of P and E core usage as well as overall CPU usage. You’ll get these automatically if you’re running App Tamer on an M1-powered Mac.

[…]

When you click on an app in the process list to change its settings, there’s an additional “Run this app on the CPU’s efficiency cores” checkbox, as you can see in the screenshot below.

I explained the basics of this feature in a previous post. It works like App Tamer’s other CPU-saving capabilities in that it’s applied to an app anytime that app is not frontmost. If you turn on the checkbox for Safari, any time that you leave Safari running in the background while you’re using another app, Safari will be switched to the processor’s E cores. This saves power and leaves the P cores free to handle higher priority tasks.
