Overview
--------
ktune provides the ktune service, which sets several kernel tuning parameters
to values suitable for certain system profiles. Currently, the only profile
provided is for large-memory systems running disk and network-intensive
applications. These settings do not override settings in /etc/sysctl.conf or
on the kernel command line. ktune may harm performance on some systems and
workloads, so it should be tested under production-like conditions prior to
production use. If ktune is found to harm performance, the settings may be
reverted without rebooting by stopping the ktune service.
Using ktune
-----------
To start ktune you can start the service with the service command:
service ktune start
If you want to enable the service in the system, use the chkconfig command:
chkconfig ktune on
More Information
----------------
Please have a look at /etc/sysconfig/ktune and /etc/sysctl.ktune for tuning
parameters.
