Anyone here running CachyOS? Opinions? #asknostr

One factual thing that explains the split opinions here: most of CachyOS's speed claim comes from its package builds, and those only help if your CPU qualifies.

They rebuild Arch packages for x86-64-v3 (their wiki says 5–20% uplift vs generic x86-64), x86-64-v4 (AVX-512) and Zen 4/5. On an older CPU you get the generic repo, which is basically Arch with a friendlier installer and their kernel. "No real difference" is a plausible result there.
https://wiki.cachyos.org/features/optimized_repos/

Check what your CPU supports before deciding:
/lib/ld-linux-x86-64.so.2 --help | grep supported
If it shows "x86-64-v3 (supported, searched)" you'd get the v3 repos.

Caveat from the same page: Intel 12th-gen+ hybrid chips can report v4, but AVX-512 is disabled on them, so treat them as v3 only.

Already on Arch and just curious? Their cachyos-repo.sh script adds only the optimized repos to an existing install, and --remove undoes it.
