    You are right.
    https://openbenchmarking.org/innhold...3b4c29125791de

    Which means it relies upon what ffmpeg buildsystem detected vs what was overriden (not a lot, see table on first page of article).
    And actually uses different archive for Windows, it could be prebuilt for Windows as no Windows compilation flags are listed on first page. Therefore this test might be misleading, as it might neither compare out of the box performance (if Ubuntu packages are not used) nor real OS performance (in which case software would be compiled with the same flags on both OSes).

    Ubuntu has patched systemd in the 19.04 repository so the Dingo can boot on Ryzen3000/x570 although the installer .iso hasn't been updated. Now that 18.10 is dead, you can change software sources to notify for all upgrades, apt update, then run:

    Code:
    sudo do-release-upgrade
    to upgrade an existing 18.04 to 19.04.

    Probably not useful for testing/comparing purposes as it won't be a "clean" install, but for those of us with Ryzen 3000 series CPUs and a need to run a 5.x series kernel, this will work.

    Interesting results! I’m wondering if anybody out there has any idea why Windows is so much slower with PyBench and other interpreter tests? It just seems strange that both Python and PHP failed so badly compared to Linux.

    So, unless I missed it; this is 18.04 LTS running the "stock" Kernel which should be 4.15 correct? Impressive indeed. I would like to see the results running the latest Linux kernel.

    Actually, it's AMD who has to release the fixed microcode. They had a version out, but had to pull it because it was causing instability.
    But my post was just tongue-in-cheek

    Interesting - seems the Windows scheduler has dramatically caught up. Still obviously has a lot more work to do. I wonder what's going on with Linux and ffmpeg.

    Also, I'm a big fan of the 2nd to last comparison graph, though as a suggestion:
    I'd like to see it sorted based on the percentage
