[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 expect. 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.

I mean "TCP" not "TFTP" in the mail.
