I've had experience with the "performance" setting, and I can confirm
that it turns your computer into a space heater.

It did grant a significant performance boost compared to the "ondemand"
governor setting when I was desperate for extra frames per second when
using wine many years ago on underpowered hardware.

I would not recommend ever using that setting since it's the
CPU-equivalent of crypto-mining with your GPU; it's constantly
redlining and stressing hardware.

As an aside, the OP may be interested in investigating the scheduler
being used:
