If you operate in VPS environments other than Virtuozzo-based ones
(Virtuozzo containers or OpenVZ containers), you can also switch Plesk
to VPS-optimized mode.
To switch Plesk to the VPS-optimized mode in a non-Virtuozzo
environment run the following command:
PRODUCT_ROOT_D/bin/vps_optimized --turn-on, where
/usr/local/psa for RPM-based systems
/opt/psa on DEB-based systems.
To improve the Plesk resources consumption, update the
/etc/my.cnf by adding the skip-bdb line to the
[mysqld] section, and restart
Although it is not recommended to use SpamAssassin and Plesk Premium
Antivirus while operating in the VPS-optimized mode, you can still do
that. The following instructions help you optimize these services:
To optimize Plesk Premium Antivirus resource consumption, open for
/etc/drweb/drweb32.ini, set PreFork = No, and
restart the service.
To optimize SpamAssassin resource consumption, run the following
command after performing the initial Plesk configuration:
/usr/local/psa/bin/spamassassin --update-server -max-proc 1
Plesk administrators have the option to use Plesk for their own needs by
only leaving relevant controls in the UI and removing all those related
to shared hosting business (resellers, service plans, subscriptions). To
enable this simple and lightweight user interface, run the following
