Hi Jeremy,
Thanks for the info. I ran another test with a 100MB file as below:
mount -t smbfs //machineb/share /mnt/machineb ....
cp test-100mb.dat /mnt/machineb/test1.dat
umount /mnt/machineb
The above copy took 60 seconds.
mount -t cifs //machineb/share /mnt/machineb ....
cp test-100mb.dat /mnt/machineb/test2.dat
umount /mnt/machineb
This copy took just 20 seconds.
I am running kernel 2.6.8 which apparently has CIFS built in.
I am amazed by the performance increase, so CIFS definitely seems the way to
go. Is there a deep reason for why this is, as CIFS seems to be part of the
SAMBA team (http://linux-cifs.samba.org/) so it seems weird that they have
both the smbclient and CIFS client with such massive performance
differences....
Thanks again,
Roger

Can you try using Steve French's cifsfs client instead of smbfs. Steve
is actively maintaining cifsfs and is working on performance issues.
Jeremy.
