Subject: How to change delayed ACKs?

I play online games.
Someone told me about Leatrix Latency Fix.
http://www.wowinterface.com/downloads/info13581-LeatrixLatencyFix.html

ACKs are delayed. The latency fix works by changing setting to
decrease that delay.

On Windows it modifies 'TCPAckFrequency' in the registry.

On FreeBSD and Mac OS X;
sudo sysctl -w net.inet.tcp.delayed_ack=0

This key doesn't seem to exist on Linux.
error: "net.inet.tcp.delayed_ack" is an unknown key

Is there any way to reduce the delay of delayed ACKs in order to
increase performance in online gaming?
