--- Comment #10 from WANG Xuerui <xen0n at gentoo dot org> ---
My 2 cents: while I have reproduced the slowdown and verified the insight that
sched2 is the culprit, I'd say from a Gentoo packager's perspective that this
kind of extreme slowdown are rare in practice, and we probably shouldn't simply
disable the problematic pass for all code. xry111 already confirmed sched2's
contribution to performance in comment 5, and I agree with Mingcong in comment
6 that the performance impact is to be measured before any action is taken.
