Here is some news that both excited me and gave me pause. In its annual 2025 retrospective, published today, Arch-based CachyOS, widely popular among Linux gamers and heavily focused on performance optimization, reveals plans I did not expect: an expansion into the server space.

“In addition to our ongoing PGO and AutoFDO optimizations, we are developing a specialized ‘Server’ Edition for NAS, workstations, and server environments. We intend to provide a verified image that hosting providers can easily deploy for their customers. This edition will ship with a hardened configuration, pre-tuned settings, and performance-optimized packages for web servers, databases and more!”

V2 is about Nehalem. V3 is approximately Haswell (iirc it corresponds to some least common denominator of AMD and Intel from around that time). V4 needs AVX512 (that is really the only difference in enabled instructions compared to V3).

Both my daily driver computers can do v3, but not v4. (I like retro computing, so I also have far older computers that can't even do 64-bit at all, but I don't run modern software on those for the most part.)

Have you tried Gentoo? I’ve heard you can compile things for your hardware, I’d love to try it, but I have very little free resources lately. So, some day. I’m curios whether the impact is worth it, the whole compiling chore.

I ran Gentoo from 2005 to 2009 or so. Took too much time compiling the software, nor doing that again. Apart from that it had some pretty neat ideas.
