    Hmm, I thought the patch was only supposed to make a real difference
    if you have multiple devices? But you only got a single disk.

    At least that was the case it was supposed to fix: starvation of fast
    devices from slow devices.

    Ok perhaps the new adaptive dirty limits helps your single disk
    a lot too. But your improvements seem to be more "collateral damage" @)

    But if that was true it might be enough to just change the dirty limits
    to get the same effect on your system. You might want to play with
    /proc/sys/vm/dirty_*
