Squeezing More Performance Out Of An Intel Celeron "Alder Lake" CPU With A Faster Linux OS

[mangeek]

Wow. I've read Intel's doc on how they optimize Clear Linux, and I've heard some people dismiss the notion of 'raising the floor'. What I'm curious about is whether Ubuntu could have sub-arches of x86_64 compiled for things like 'x86-64-v3'. I know there are fresh options in glibc to do some of this at runtime, but I think that's going to be farther away than just having the repos holding a few differently-optimized copies of the same stuff. I don't even think it would have to be too granular, maybe just the default x86_64 for all older stuff, and an optimization level that gives a boost to stuff that's likely still widely deployed and vendor-supported (so... AVX2/Haswell?)

Have you tried enabling AVX-512 on this Celeron? It would be hilarious if it worked, you could blow past vastly more expensive CPUs in a handful of benchmarks.

Since Clear is pretty painful to use as a generic host due to its software distribution model, if you are wondering how to leverage some of it on your system, read these!

It goes without saying that you could also use it as a host while using Distrobox to get stuff from other distributions; it works both ways.
Not the first time I point this out in the comments, so hopefully it's on-topic enough and proves useful to someone; I think the freedom of not having to commit to a certain distribution's repositories (just because it happened to be a sensible choice as a host system) is beautiful. And as you'll see in that second link, there should be no performance overhead attributable to the container itself.
Cheers.

Interesting, thx!

Those Firefox differences are *really* big. I wonder if some distributions are messing up their build options?

Same CPU governors... Looks like Clear and OpenSUSE are using transparent hugpages...

For comparison purposes, it'd be nice to have the flatpak Firefox on the charts. It's built by Mozilla.

Does installing Brew + Snap + Flatpak on Clear sort of solve the issues of Clear's software distribution model in terms of using it as a desktop OS?
