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
|
|
|
|

Please have a look at /etc/sysconfig/ktune and /etc/sysctl.ktune for tuning
|
|
parameters.
