2. Solaris
Dear all,
I have a Local zone , where users feel that performance is not good.
Is it wise to collect the inputs from the local zone rather than taking from the global zone.
And also Can I tune from Global zone , so that it will reflect in local zone.

tuned-main.conf(5) tuned-main.conf file format description tuned-main.conf(5)
NAME
tuned-main.conf - Tuned global configuration file
SYNOPSIS
/etc/tuned/tuned-main.conf
DESCRIPTION
This man page documents format of the Tuned global configuration file. The tuned-main.conf file uses the ini-file format.
dynamic_tuning=BOOL
This defines whether the dynamic tuning is enabled. It is boolean value. It can be True or 1 if the dynamic tuning is enabled and
False or 0 if disabled. In such case only the static tuning will be used. Please note if it is enabled here, it is still possible to
individually disable it in plugins.
sleep_interval=INT
Tuned daemon is periodically waken after INT seconds and checks for events. By default this is set to 1 second. If you have Python 2
interpreter with applied patch from Red Hat Bugzilla #917709 this controls responsiveness time of Tuned to commands (i.e. if you
request profile switch, it may take up to 1 second until Tuned reacts). Increase this number for higher responsiveness times and
more power savings (due to lower number of wakeups). In case you have unpatched Python 2 interpreter, this settings will have no
visible effect, because the intepreter will poll 20 times per second.
update_interval=INT
Update interval for dynamic tuning (in seconds). Tuned daemon is periodically waken after INT seconds, updates its monitors, calcu-
lates new tuning parameters for enabled plugins and applies the changes. Plugins that have disabled dynamic tuning are not pro-
cessed. By default the INT is set to 10 seconds. Tuned daemon doesn't periodically wake if dynamic tuning is globally disabled (see
dynamic_tuning) or this setting set to 0. This must be multiple of sleep_interval.
EXAMPLE
dynamic_tuning = 1
sleep_interval = 1
update_interval = 10
