on NetBSD -current with patch, pentium 133, 192MB RAM, 80GB Seagate
barracuda ATA.
another machine were doing
dd if=largefile bs=64k of=/dev/null
file was 512MB >> size of memory, so disk I/O were included
dd said 9.2MB/s!!!!!!!!!

cat largefile >/dev/null gives similar results
that's LARGE IMPROVEMENT.
nfs writes peaks at 5MB/s with 100% CPU load, no improvement.
PS. i won't give results when i run linux on that machine, because with
10Mbps ethernet it was a problem to saturate ;)
