Is there a Macintosh version?
Leatrix Latency Fix isn't supported on Macs. However, you can achieve lower latency in OSX by entering the following command in a terminal window. This will disable delayed acknowledgements until you restart your computer.
sudo sysctl -w net.inet.tcp.delayed_ack=0
To disable them permanently, create a text file under "/etc/" called "sysctl.conf" and copy/paste the following line then restart your computer.
net.inet.tcp.delayed_ack=0
To set things back to default, just delete the "sysctl.conf" file and restart your computer.
