    I am wondering if this really makes the system tailor your hardware better, with all its potential. Has anyone done measurements?

      If you want a system wide performance boost you need to rebuild everything rather than just the kernel. You’ll typically see a 10-15% performance boost by building everything for a more modern target like x86-64-v3 (Skylake era) over x86-64. Again, that’s rebuilding the entire OS - all packages - not just the kernel. I think phoronix has some benchmark numbers on this from a couple of years ago if you want to dig into it. On Arch there’s an unofficial repo that builds everything for the -v3 target and people seem to have good results. I think RHEL and/or Fedora were considering moving the entire distro to v2 or v3 but I haven’t paid attention to how that turned out.

      Edit: here’s the arch user effort for -v3, it looks like all of the harting.dev links are dead: https://somegit.dev/ALHP/ALHP.GO

        cachyos is an arch-based distro, which has a large repository for v3-compiled binaries and soon they’ll have also repo for v4. kernels are already compiled for v3 and v4. it’s also by far my favorite distro at the moment.

          Anything 1xxx series or later for sure. I’m not sure what the lower bound is.

          What does /usr/lib/ld-linux-x86-64.so.2 --help say on the system you’re wondering about?

          -v2 is just about everything after 2011ish, if it was made more recently than 2016 -v3 almost certainly is supported.
