Quote of the week

MuQSS has been slowly bitrotting since well before the world turned to this; it's never behaved with /proc/pressure/ enabled and trying to use it on my Ryzen just turns every idle into a prolonged hang. If there's a magic combination of settings necessary for stability, it just wasn't documented anywhere.

Mainline CFS used to be really bad up until the Wasted Cores paper came out with hard data (and confirmed I wasn't completely crazy). It's since mostly caught up to the point where the difference doesn't matter. The gradual influx of RT patches is probably helping a lot too.

I guess it's time to let it go. But for a while there, CK's code let me feel like I'd never need another upgrade after 2010.
