I ran some bonnie benchmarks back in December on NetBSD 1.0 and FreeBSD 2.0
and saw about 2-3MB/s for NetBSD, 3-4 MB/s for FreeBSD.  I don't know why
there should even be much difference.  Those were P5-90s, ncr sc200,
Q1080s.  I'm running IBM 0662 drives now that reach over 4.3MB/s on block
reads in bonnie, simply outstanding (200MB file, I didn't believe the 100MB
numbers, but they were true).

Tip of the cap to Stefan and Wolf, they've done a better job than any
commercial outfit I'm aware of.  Truly a beautiful hack.

Cheers,
