A quick Linux network performance tip: iptables


By Joe Dolittle

Here's a quick tip if you want to improve your system's performance and you're not doing any routing: turn off iptables.

The iptables system uses a few cycles from your CPU -- constantly -- and doesn't really add value if you're not routing traffic. So turn it off.

Here's how:

 #service iptables stop
 #service ip6tables stop
 #chkconfig iptables off
 #chkconfig ip6tables off

Pretty simple. Enjoy faster Linux computing!
