I started a bonnie++ run, but afer 1.5 days killed it ;-)

Here are simpler results:

On nfs: /usr/bin/time  dd if=/dev/zero of=./test bs=1m count=64
64+0 records in
64+0 records out
67108864 bytes transferred in 123.054 secs (545361 bytes/sec)
      123.67 real         0.03 user        70.36 sys

On local scsi disk: /usr/bin/time dd if=/dev/zero of=/tmp/test bs=1m count=64
64+0 records in
64+0 records out
67108864 bytes transferred in 98.470 secs (681515 bytes/sec)

This is on a
