How does this compare to the default these days? CK used to focus on getting things working on one core or a low number of cores better. Most folk have at least 4 cores these days is MuQSS competitive as you increase the core count?

"I've extended the runqueue sharing options to all CPUs as well, meaning it can be used in NUMA hardware as a single runqueue if desired."

It looks like some thought was put into that.

Have his patches even been something that you can really benchmark though? Last time I tried them I really couldn't tell any difference, but a lot of people claimed that the desktop was more responsive.

bfs was simple, is muqss also?

I typically use the Zen kernel. How does CK's patchset differ from Zen?

It's on their website. Look at the diffs. http://zen-kernel.org/. Among other things, Zen usually includes CK patches, well not always. What frustrates me is that many times Zen make out release without including CK/MuQSS because their release time do not align (my speculation). One day you running 4.19.x with MuQSS, other day you run 4.20 without MuQSS. I recommend Liquorix for Debian/Ubuntu/Gentoo distros, it is much more predictable, at least they don't remove/add CK patches whenever they feel like it.

I don't know about other distros but on Arch with linux-zen MuQSS isn't used, so it doesn't matter if it's already in the repo or not. It's always just using the optimized CFS from Zen
