[Samba] Slow samba access from Mac OS X 10.2.6

[James Blackburn]

Just to let you know I've solved the slow mac client problem thanks to 
Ben Low.

The issue was with this line:
socket options = IPTOS_LOWDELAY TCP_NODELAY SO_SNDBUF=4096 
SO_RCVBUF=4096
Removing SO_SNDBUF and SO_RCVBUF fixes the issue.

I think this was in the default configuration - or the default for 
swat.  Perhaps it shouldn't be?

Hope this helps anyone else with complaining mac users.
