Manjaro Linux CPU Performance Mode?

How to set CPU Performance Mode in Manjaro Linux?

[Master Disaster]

cpupower frequency-set -g performance

Its important to note, if you have an Intel Laptop running a Sandy Bridge or newer CPU this might not do anything since these CPUs have their own driver package to handle Power States. Unfortunately I'm not familiar enough with Manjaro to know the specifics.

I tested switching to performance governor on my i5-8250u. It does make a difference (I compared the speed of matrix multiplication in numpy before and after switching).

I would consider using the gamemode utility made by feral.

This allows to switch the CPU to performance only when running a given app, so the usual power saving and such remains intact (when the app is not running of course).
