I am not really sure.  The samba help talks about 2 options:

TCP_NODELAY  This effects the transmit side right, sending before the
             buffer is filled
IPTOS_LOWDELAY   (is this the same as delay ack)

Anyway I want to try to see what gives with my poor performance between
win2k and my samba server running on netbsd.

The message before talked about delayed ack, so I will start there.

Any help appreciated.
