1.12. Using Network Kernel Tunables with sysctl

Using certain kernel tunables through the sysctl utility, you can adjust network configuration on a running system and directly affect the networking performance.
To change network settings, use the sysctl commands. For permanent changes that persist across system restarts, add lines to the /etc/sysctl.conf file.
To display a list of all available sysctl parameters, enter as root:
~]# sysctl -a
