See my answer I posted earlier - I used these socket options (on Linux 
on ARM):

socket options = TCP_NODELAY IPTOS_LOWDELAY SO_KEEPALIVE SO_RCVBUF=4096 
SO_SNDBUF=4096

Also, this page lead me to set the buffers lower:

Samba just logged that the client had disconnected, which was only 
partially true, because the client certainly didn't want to connect.
