Bob,
I saw the earlier posting earlier and thought I would throw my $0.02 in as well.
I ran the test using the following four machines:
eugsrv1- Dual PII 350, 512 MB Ram, Intel 82559 Fast Ethernet NIC, LVD-SE Drives
lnxets1 - PPro200, 196 Mb Ram, 3Com 3c595 100baseTx - SCSI2 Drives
lnxets2 - Dual PPro200, 256 Mb Ram, 3Com 3c595 100baseTx - SCSI2 Drives
nfsets2 - Dual Sun UltraSparc II, 2 Gb Ram, A10000 Raid Array (mode 5) - Ultra160
Drives
Here is what I saw with a ~27 Mb file.
[root@lnxets1 /]# mount -t nfs -o nfsvers=2 lnxets2:/scratch /mnt/tmpmnt

SMB sucks for performance. That is all there is to it. NFS Vers 3 should give you much
better performance than you are seeing. I would guess you are either having a network
problem, you have a bad NIC, or the NFS software you are using really blows. I would
recommend using
either Interdrive 5.0 or maybe Reflectios NFS. Both are decent nfs clients.
