Tuned is a daemon that monitors and collects data on the usage of various system components, and uses that information to dynamically tune system settings as required. It can react to changes in CPU and network use, and adjust settings to improve performance in active devices or reduce power consumption in inactive devices.

The accompanying ktune partners with the tuned-adm tool to provide a number of tuning profiles that are pre-configured to enhance performance and reduce power consumption in a number of specific use cases. Edit these profiles or create new profiles to create performance solutions tailored to your environment.

Further information about tuned and ktune is available in the Red Hat Enterprise Linux 6 Power Management Guide, available from http://docs.redhat.com/.
