  • Post #337550

    Had some quality time with claude debugging a slowness with AHCI/scsi and aio=io_uring. See below link for details (patch 1 is where it&amp;#39;s at), but tldr is up to 60-80x improvement in performance for the case that hits ppoll idle all the time. https://lore.kernel.org/qemu-devel/20260213143225.161043-1-axboe@kernel.dk/
