[Samba] Poor performance between linux boxes using Samba 3

I have a network with two machines on it, both running Debian and updated
with the latest Debian stable samba (3.0.14). Both machines are reasonably
high spec (512MB RAM and Athlon 2200+ processors) and have little else
running (console mode, no KDE/Gnome/etc). They are connected by a Netgear
FS108 100-Base-T ethernet switch.
When I try to copy a large file (500MB) from machine A to machine B using
FTP (Machine B running vsftpd) then I get 9.5 MB/sec throughput, so my
100-base-T network is running at full speed and full duplex, as I would
When I instead try to copy the same file from machine A to machine B using
FTP (Machine A running "smbmount -t smbfs //machineb/share /mnt/machineb -o
user=xxx,password=xxx") then I get much lower throughput - around 3 MB/sec.
I have followed the instructions in the HOW-TO and in the smb.conf file and
have the settings below on both machines.
The smb.conf has the following line:
socket options = TCP_NODELAY SO_RCVBUF=8192 SO_SNDBUF=8192
Is this throughput normal ?
I would have expected similar performance to the FTP, given the spec of the
machines and the fact that both protocols are using TFTP.
Thanks in advance.
