Only one warning, the write perf is only 4-4.5MBytes/sec.  The drive buffer
is too small...  I have even tried to modify the FreeBSD clustering code,
and cannot get any better than that.  Since you usually wait on reads more
often, it isn't all that bad.  But my read perf still stands, it is really
fast.
