tuned-adm - commandline tool for switching between different tuning profiles
This command line utility allows you to switch between user definable tuning
profiles. Several predefined profiles are already included. You can even
create your own profile, either based on one of the existing ones by copying
it or make a completely new one. The distribution provided profiles are stored
in subdirectories below /usr/lib/tuned
and the user defined profiles in
subdirectories below /etc/tuned
. If there are same profiles on both
places, user defined profiles have precedence.

somebody modified sysfs/sysctl value by hand). Detailed information what
is checked, what value is set and what value is expected can be found in
- 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
recommend profiles targeted to the best performance or balanced profile if
