Macos – TCP Optimizer for OS X

macostcpip

Does anyone know of a utility similar to SpeedGuide.net's TCP Optimizer or some other way to accomplish the same thing on Mac OS X (preferably with Snow Leopard)?

You can always check out any Linux based howto on this topic, Mac is also only a Unix system. Most guides you'll find online are targeted towards servers (although Mac based servers are really rare). The following was taken from ESnet:

Apply these settings to /etc/sysctl.conf, and reboot:
# set this for hosts connected at 1GE or higher
net.inet.tcp.win_scale_factor=8
# for 10G hosts it would be nice to increase this too, but
# 4G seems to be the limit for some OSX installations
kern.ipc.maxsockbuf=16777216
