I'd like to bring attention to the ALHP repos[1].
These are the Arch packages built for x86-64-v2, x86-64-v3 and x86-64-v4, which are basically names for different sets of x86-64 extensions. Selecting the highest level supported by your processor should get you most of the way to -march=native, without the hassle of compiling it yourself.
It also enables -O3 and LTO for all packages.

- eru 2y agoNice, I'll try them out! LTO is great, but I have my doubts about -O3 (vs the more conservative -O2). UPDATE: bah, ALHP repos don't support the nvidia drivers. And I don't want to muck around with setting everything up again. Another update: I moved to nvidia-open, so now I can try the suggested repos.

- eru 2y agoWell, I moved to the new repos. But I had to change to the dkms drivers. Seems to work so far, but nothing 'feels' faster either.
- alessandroberna 2y agoYou should be able to use the regular arch repos as a fallback (and even repos from alhp with a lower feature level https://somegit.dev/ALHP/ALHP.GO/issues/255#issuecomment-3335 https://somegit.dev/ALHP/ALHP.GO/issues/255#issuecomment-333...) doing this should allow you to use as many optimized packages as possible while still being able to install packages not supported by the alhp
