IPC with socket connection?

[lbland]

hi-

I have two processes running on the same computer communicating with 
sockets created with AF_INET. It works extraordinarily well. I choose 
all the normal stuff to make the sockets, but I think if I choose some 
other flags, specific to IPC on the same computer, then the connection 
will be much more optimized.

Where should I look for optimization flags? I looked in all the normal 
places, but can't find any.

TIA-
