Been running PF-Kernel for a few years, which has a bunch of patches, including BFQ, ck patch set with BFS, Tux in ice, UKSM, and grayskys gcc kernel patch. I normally just use the PF Github repo
Love it. With BFQ, you no longer get system pauses on your desktop. I can listen to music or play a video, run a few vms, while a compiler runs in the background, and x-windows doesn't pause, typing doesn't pause, its how a system should act. Your system seems more fluid with no pausing.
PF-Kernel seems to be for Arch/Gentoo/Rpm based, but I've used it on Ubuntu systems. Pf-Kernel isn't the only one, there are other kernels out there that include more performance patches, Xanmod and Liquorix
