Just a thing to check, but make sure that RAID array isn't running in
degraded mode.  If one of the disks failed, or it thinks the array is
out of sync with itself, then everything you would have read from the
failed disk has to be reconstructed from the other three, and
performance goes to lunch.  It's been awhile since I used software RAID
on Linux, but /proc/mdstat should be the file that shows you the status.
