    Well, but at the beginning I've got about 85-90MB/sec for buffered array
    reads. That was on 2.4.21-pre or even patched 2.4.20 (on siimage - in it's
    early stages, not sata_sil driver). Now it's 3 times slower (checkedwith
    preemptible kernel, it's even slower) - so something went bad.
