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
#service ip6tables stop
#chkconfig iptables off
#chkconfig ip6tables off
Pretty simple. Enjoy faster Linux computing!
