in case you are like me not willing to watch through a 10 minute video to get information that can be read in 2 minutes, here is a text article about the stuff he talks about:
Spoiler: It requires clang compiling the kernel.
You need clang for 88% improvements - but the 77% for gcc isn’t that bad either! If it works for me, that should take it down to the 1 minute range…
That must have been quite a rampage though the headers to produce THAT improvement! Hopefully the dev gets the props he deserves for this!
Up to…
On my rig I get around ~40% with defconfig and 60% (gcc compiled) with the arch kernel config. Still quite an improvement though.
