Optimise MySQL :-



max_allowed_packet = 1M

max_connections = 300

max_user_connections = 35




quick max_allowed_packet = 16M

IInnoDB :-

If you want to reduce memory utilisation, you must change all of your Database InnoDB tables to MyISAM. Memory utilisation is an important consideration in a web hosting server setup. We recommend that you avoid using InnoDB because it consumes a lot of memory. It has a minor influence on website load speeds, but it allows database tables to be accessed with a substantially smaller memory footprint. This can be changed using WHM PHPMyAdmin.

To modify this in PHPMyAdmin, go to the Panel SQL Section and click on your database.


Now click on the “go.”

Performance Schema :-

For MySQL 5.6.6+, you need to disable performance_schema. This is normally enabled by default and consumes a lot of server memory!

To Disable Performance_schema:–

Open my.cnf (typically @ /etc/my.cnf) via SSH or Virtual private server admin panel credentials >> add this line under [mysqld] >> performance_schema=0

Save/close my.cnf and then restart mysql service.

Other cPanel User Backup Type:-

In place of the default compressed backups, incremental backups should be used. In exchange for improved performance, this requires more room. Incremental backups are easily configured in the WHM Panel:-

WHM Home >> Backup >> Backup Configuration

PHP-FPM Settings for Better Optimization:-

Reduce the memory_limit setting in your php.ini file. You can change it at the specified location,

WHM Home, then click “Service Configuration”. Click on PHP Configuration Editor then “Core”  then “memory_limit”
