Yeah I saw that one. But that only changes the delayed ack...

The default value of 100ms seems fairly reasonable unless you're
talking about a LAN..

I guess what I really want to do is disable Nagle in the tcp stack, but
since you do that with the sockopts call on a per socket basis I'm
guessing there isn't any system wide tunable for it..

Thanks,
