    can you make a benchmark with BTRFS space_cache=v2 with clear_cache and discard=async?

    for each file system there are show the default options, and i take that NONE as the IO scheduler
    Thanks. Yes, that probably makes sense.

    I think this is shown in the first box, the one with system details, and i take it from there that "None" was de default IO scheduler for all (AFAIK ubuntu defaults to None for all nvme drives)

    Great article

    What IO-Scheduler was used? It is likely it would affect the Application Start-up times a lot. Michael could you re-run the test with different IO schedulers like mq-eadline, bfq and none?

    I used F2FS for months last year on my Gentoo installation. Zero problems!

    Understandable, but let me add my +1 for running including ZFS _when possible_ in these comparisons. (I use only ZFS everywhere except for /tmp-like storage)

    Well I tried using F2FS and while it works, I had to disable automount because it required a file system check at boot time, which then slowed down boot time. Sigh.

    I think I'll just do XFS in the future, see how it goes.
