Ok, here's the new results:
mount command used:
mount starsu00:/data01 /test -ohard,intr
[tdavis@pdsflx16 bonnie]$ ./bonnie -d /test/b -s 1024 File '/test/b/Bonnie.11787', size: 1073741824 Writing with putc()...done Rewriting...done Writing intelligently...done Reading with getc()...done Reading intelligently...done Seeker 3...Seeker 1...Seeker 2...start 'em...done...done...done... -------Sequential Output-------- ---Sequential Input-- --Random-- -Per Char- --Block--- -Rewrite-- -Per Char- --Block--- --Seeks--- Machine MB K/sec %CPU K/sec %CPU K/sec %CPU K/sec %CPU K/sec %CPU /sec %CPU 32768 1024 5180 75.6 5814 12.1 2770 7.3 6144 92.0 10308 7.9 290.3 4.7 8192 1024 5298 81.1 7138 17.2 4270 17.8 4826 70.1 9980 13.3 389.1 6.2
from /proc/mounts (mount command doesn't give you the rsize/wsize)
starsu00:/data01 /test nfs rw,v3,rsize=32768,wsize=32768,intr,addr=starsu00 0 0
so, 32k wsize slows you down some. 32k rsize speeds it up alot though..
