ALHP support

Greetings everyone, has anyone tried getting ALHP repository up and running? Having it above Arch repositories is useless because base packages are not replaced (and you can't make use of the x86-64-v3 optimizations) and having them above Artix repositories breaks the system.

Any plans on compiling packages with same optimizations then? It would benefit the performance a lot.

What kind of optimizations are we talking about here?

Compiler optimizations like -O3, linking, etc.

In theory (and only for very niche workloads), you get a performance benefit (cleary not if you gaming, or do normal office works or internet browsing).

Like said. Never. There exist tons of benchmarks: https://www.phoronix.com/review/linux-kernel-o3

I cant use google, but on phoronix site, you can find a ton of comparsions about vanilla compiling optimizations, and more "hardcore" optimizations (wich often makes trouble with programs, wich are programmed to be able to run on every architecture).


Edit:

Where the -O3 optimized kernel build was of some advantage was within server workloads. However, that's likely least where server administrators would be comfortable with the -O3 optimizations given the possibility -- at least historically -- of the optimizations generating incorrect/faulty code especially where in the context of the kernel could be subtle, hard to debug run-time issues.

When it came to the -O3 kernel build for other workloads like gaming/graphics, web browsing performance, and various creator workloads there was no measurable benefit from the -O3 kernel.

Edit2: Thats now only for the Kernel. But on phoronix exists benchmark with totaly whole os optimized. For further information, you could search for gentoo benchmarks.

You can specify packages from a repo, so if you had it at the end of the list, you could do say pacman -S reponame/pkgname then put those in /etc/pacman.conf e.g.  IgnorePkg = pkgname then when you see an update comes in use pacman -S on those again, which will over-ride the IgnorePkg. This would work OK if you just wanted a few key ones.
