hey david,
are you by any chance running OSX 10.4.8?
we had the same problem and it was related to samba & OSX (10.4.8). OSX
to an W2k3-Server was fine. so we thought it might be samba. but after
downgrading OSX to 10.4.7 everything was fine again. so the apple update
must have changed/ broken something. we did not look deeper into it. on
google groups we found one posting with the same problem but between OSX
and W2k. ftp, etc. was fine on OSX, only smb/ cifs was slow
hope this helps (anybody)

Here's a weird one that may have nothing to do with Samba and more to do
with network frame sizes.
I have recently upgraded the network infrastructure to support gigabit
speeds.
- OSX Tiger to OSX Tiger file transfers operate at gigabit speeds.
- Samba 3.0.23C (Suse 10) to OSX Tiger file transfers operate at gigabit
speeds.
- BUT OSX Tiger to Samba 3.0.23C (Suse 10) file transfers operate at
1-2meg/second which is well down from expected performance.
The strange thing is if I begin a file transfer from OSX Tiger to Samba
and in a terminal window on OSX begin an SCP copy operation to the same
Suse server the file transfer speed of Samba jumps up to gigabit level
speeds. As soon as the SCP copy operation is stopped the Samba file
transfer process drops to 1-2meg/second again.
My guess is this has something to do with network frame sizes but I
don't really know.
The gigabit card on the Suse box is a low-end model but the fact that
downloads and non-Samba related uploads appear to work fine (with low
CPU usage in all cases) suggests this is more to do with inbound SMB
packets rather than the hardware itself.
Any hints/pointers would be appreciated.
Regards,
David
P.S. Sorry I thankfully do not have any 'real' Windows machines to test
performance on.
