Do a Gentoo test with correct compilation parameters! Or just Arch, Fedora or Opensuse Tumbleweed okay.

To be honest, Ubuntu likely has nothing to do with it and I find the headline therefore misleading. It’s mostly the Linux kernel from how it reads.

Ubuntu 23.10 was run for providing a clean, out-of-the-box look at this common desktop/workstation Linux distribution. Benchmarks of other Linux distributions will come in time in follow-up Phoronix articles. But for the most part the Ubuntu 23.10 performance should be largely similar to that of other modern Linux distributions with the exception of Intel’s Clear Linux that takes things to the extreme or those doing non-default tinkering to their Linux installations.
