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 ;)
