I would get sambe running on my local network here but the only windows
box i have has a cruddy 10mbit card (my other boxes are 100mbit), perhaps
later tonight I can get this up and give you guys some tips.
(I've had samba tuned up before, it's just been a while and several major
releases of samba since) :)

Another shot in the dark, try compiling/enabling TCP_NODELAY or something
that looks like that.

Please tell us if it solves your problem.

thanks,
