As part of investigation on what OS out there now would be best for
a pc-workstation cluster, I obtained the following bonnie results.
(include all standard benchmark disclaimers, etc. etc.)
"bonnie" disk benchmark, using a 100 MB file:

The hardware configuration for for all tests is identical, Intel Plato mb, 64MB,
ncr scsi, Quantum 1080S (sd0), Seagate ST12400 (sd1).
"1.1.59 sd0" is Linux 1.1.59 ext2fs Quantum 1080s
"1.1.5" is FreeBSD 1.1.5.1 ufs, running 1.1.5.1 Quantum 1080s
"1.0" is stock NetBSD 1.0 ufs Quantum 1080s
"1.0**"is NetBSD 1.0 ufs after "tunefs -a 8 -d 0 /dev/rsd0e" Quantum 1080s
"1.0*" is FreeBSD 1.1.5.1 ufs, running under NetBSD 1.0 Seagate ST12400N
"2.0**"is stock FreeBSD 2.0 Quantum 1080s
"2.0*" is FreeBSD 1.1.5.1 ufs, running under FreeBSD 2.0 Seagate ST12400N
The Linux performance looks a little off from what I recall, so I'm going to try
again with a 1.1.64 kernel this week. The NetBSD 1.0 results are good
for the Quantum but (partly) poor for the Seagate drive. And the FreeBSD 2.0
numbers are almost too good to be true--is it possible to get almost 4 MB/s out
of these drives? In any event, these are very impressive numbers for all three
OSs
