Your computer is doing fine because windows on arm scheduler is so messed up, that it sets priority wrong.
In normal windows if you set FAHCore to anything other than normal, things just start to go to hell
Thanks for the info.
But since we cannot expect Microsoft to improve things anytime soon, this manual fix is still a huge win.

I really really really don't think this is a fahclient issue. FAH does not develop windows scheduler.
Giving fahcores above normal priority is bad idea, as computer will become unresponsive. Whatever is messed up on ARM windows, is ARM windows issue, and not FAH issue
That's exactly how Windows scheduler works on Intel CPUs with E-cores.
Usually setting low priority means you will get the same performance, but your process will yield more to interactive applications. Microsoft breaks this assumption, limiting low priority tasks to a slower subset of CPUs. They are trying to be smart for no reason

Wow, Talk about the Microslop.
Try playing around with thread priorities on normal CPUs, and things gonna go mental :/

Someone thinks a low priority task is the same as a background task.
