System Tuning and Configuration • How does a CPU governor work?

First off, I would like to really thank the great community here. It's hands down the friendliest Linux community I've ever continuously bothered with my newbie questions. Today I was jamming out talking heads style with the pitch bender on my MIDI keyboard with a loop of several tracks with no discernible latency or pops. I can only do that thanks to the amazing help I've had here. So thanks.

Anyway, I was wondering about the CPU governor. I have a power-profiles-daemon that can be set to: performance, balanced and power-saver. I can set the CPU governor to performance regardless of whichever of the power profiles I use but I imagine that I will get the best out of the performance governor when I set it together with the performance power profile right?

Is setting the CPU governor to performance like flooring the accelerator in a car? It just runs at top speed all the time right? Or does it alter it's frequency dynamically based on load?

The more I know, the less I know. Thanks for any input.

Best

Matt
