That's 2.5% - a huge difference. Particularly since kernel build times shouldn't even be that kernel-intensive. I think there's something else going on than the nops. Same config? There are likely many other differences between 5.10.19 and 5.12-rc3. So can you check just plain 5.12-rc3 and then 5.12-rc3 plus x86-nops, with otherwise identical configuration? Linus
