Tuned: Daemon for monitoring and adaptive tuning of system devices.

This is Tuned 2 adapted for Ubuntu systems

How to use it

First, install it on your system:

# apt-get install git git-core build-essential
# apt-get install rpm python-decorator python-dbus python-gobject python-pyudev python-configobj
$ git clone https://github.com/edwardbadboy/tuned-ubuntu.git
$ sudo make install

After the installation, restart your system.

Once tuned is running (after reboot) you can easily control it using tuned-adm command line utility. This tool communicates with the daemon over DBus. Any user can list the available profiles and see which one is active. But the profiles can be switched only by root user or by any user with physical console allocated on the machine (X11, physical tty, but no SSH).

To see the current active profile, run:

$ tuned-adm active

To list all available profiles, run:

$ tuned-adm list

To switch to a different profile, run:

# tuned-adm profile <profile-name>

And to disable all tunings, run:

# tuned-adm off

Other options:

# tuned-adm recommend

Recommend profile suitable for your system. Currently only static detection is implemented - it decides according to data in /etc/system-release-cpe and virt-what output. The rules for autodetection are defined in recommend.conf in profile directory. They can be overriden by user by putting the recommend.conf into /etc/tuned. The default rules recommends profiles targeted to the best performance or balanced profile if unsure.

Your profile choice is also written into /etc/tuned/active_profile and this choice is used when the daemon is restarted (e.g. with the machine reboot).

Available tunings

Some information about the current available tunings is available via the Red Hat Documentation over here: https://access.redhat.com/site/documentation/en-US/Red_Hat_Enterprise_Linux/6/html/Power_Management_Guide/tuned-adm.html
