Kernel tuning through the /proc filesystem.
systune [ -c, --config configfile ] [ -h, --help ] [ -v, --verbose ]
This program writes kernel parameters, previously saved in a configuration file, to the /proc filesystem. This enables kernel performance to be adjusted without recompiling the kernel.
-c, --config configfile
Specify an alternative config file. The default is /etc/systune.conf
-h, --help
Print a short explanation of syntax to standard output.
-v, --verbose
Verbose mode: cause non-existent paths in the configuration to generate error output to standard error. Without this option, erroneous paths are discarded silently.
Each definition takes a single line, in the form path:definition, where path must begin with /proc/sys/. Paths beginning with any other sequence are silently ignored.
Comments are introduced by the character #. The whole line from the # character onwards is discarded, together with any whitespace immediately preceding it.
Blank lines are ignored.
/etc/systune.conf
A file with saved kernel parameters. It is possible to generate this file with the systunedump (8) command.
