As fas as I know, most benefits in Clear Linux come from using GCC's Function Multi-Versioning, not from specific march/mtune :

This is effectively having binaries containing multiple versions of functions, optimized to target different arch
I do no see what would prevent a distro using that. No need to deprecated ancient platforms, but at least the new ones are able to use their news instructions. Else what's the point of buying Intel/AMD cpus with avx2?
Also since many distros dropped x86, maybe they could split AMD64 into 2, old and new, though that might be too much work.

This gives you an idea of why this doesn't happen.

They always show the secret souce. If you want to make use of some of their optimizations just look into their build script of a particular package.
I did that couple of times for e.g. ocatve but im running on ubuntu 18.04. The improvements are significant.
To be fair im usually more an amd buddy but what intel is doing with clear linux is really good also from the open source point of view. Proof is this benchmark ...even amd is gaining performance with it.
Btw AFAIK Solus also picked some of their patches.

Originally posted by Almindor View PostI'm surprised how the rolling release Manjaro/Arch is behind in these. It seems there's something wrong with how they build their packages. Doesn't make sense for newer to be slower in pretty much all tests.
Schedutil is slower than ondemand:

Which governor is used by the others distros?

It's not like it was not all opensource. Clear Linux's devs have documented their work and written blog posts about it.

EDIT : I specifically think about FMV, not brainless march/mtune tuning...Last edited by sheepdestroyer; 12 September 2019, 09:43 PM.

It's a developer tool not a fast everyday OS.
Edit: also, manjaro etc are not archlinux.
