NAME

tuned - dynamic adaptive system tuning daemon

SYNOPSIS

tuned [options]

DESCRIPTION

tuned is a dynamic adaptive system tuning daemon that tunes system settings dynamically depending on usage. It does so by monitoring the usage of several system components periodically. Based on that information components will be put into lower or higher power saving modes to adapt to the current usage. Currently only ethernet network and ATA harddisk devices are implemented.

OPTIONS

-d, --daemon

This options starts tuned as a daemon as opposed to in the foreground without forking at startup.

-c, --conffile= conffile

Specify the name and path of the configuration file, default is /etc/tuned.conf.

BUGS

Using NetworkManager and tuned in the same time will completely stop and start NetworkManager. The inconvenience is done by tuned, which is setting the power saving levels. This happens because the network device will loose it's physical link for a very short time when it performs a power saving switch and NetworkManager can not distinguish this from a connectivity loss. This will be resolved in future versions of tuned and NM where NM will gain the mechanism to switch speeds for network devices.
