my link to the source for this seems to be broken but here's what i have 
personally on my mac.

in /etc/sysctl.conf, add these lines:


you probably have to restart to activate them. you can set these from
the command line as well but they won't "stick", but you can try out 
settings that way.

use: sysctl -w net.inet.tcp.recvspace=4000000        (for example)

to set these values interactively.
