    Just for information: this patchset, applied to 2.6.35-rc6, gives about
    20-25% increase in speed/throughput on my desktop system
    (Phenom 2.5GHz Quadcore, 3 disks) with the tunables set according
    to what you've used/reported here (the setup with slice_idle set to 0),
    and it's measurable with fs_mark, too.

    After 2 hours of hard testing, the machine remains stable and responsive.
