Try putting this file into:

/System/Library/StartupItems/SystemTuning

(Replace the existing SystemTuning file or replace it) This means the command will run every time you reboot your Mac

You can also use Terminal to go to that directory and run

./SystemTuning

This will run those commands immediately and the effects should be instantaneous... so if you don't notice anything, don't complain, lol.

No promises, but for me it added about 20% to my frame rate and chopped the rez lag after tping and logging in to almost zero. It is a set of tips to increase network bandwidth.

CODE


#!/bin/sh

/usr/sbin/sysctl -w net.inet.tcp.sendspace=262144
/usr/sbin/sysctl -w net.inet.tcp.recvspace=262144
/usr/sbin/sysctl -w net.inet.tcp.delayed_ack=0
/usr/sbin/sysctl -w kern.ipc.maxsockbuf=2097152
/usr/sbin/sysctl -w kern.ipc.somaxconn=8192
/usr/sbin/sysctl -w net.inet.udp.recvspace=65535
/usr/sbin/sysctl -w net.inet.udp.maxdgram=57344
/usr/sbin/sysctl -w net.local.stream.sendspace=65535
/usr/sbin/sysctl -w net.local.stream.recvspace=65535

exit 0

ill admit to being a geek, but sadly im not at mymac, cause im at work... what exactly does this do? looks like you are changing the network setting, could you maybe post an explaination of what all the changes you made are and what they do?

also this should effect all information traviling over your network, so a general speed up for everything would happen, right?

thanks

jester

Again Thanks for the info, its appreciated. I do agree though that an explanation of what this does would be nice for those unfamiliar with these commands, also maybe an explanation of what those numbers are based off of.
