Speed Up MySQL and MariaDB on cPanel: What Users and Server Admins Can Do<\/h1>\n

Boost your website’s speed and user experience by optimizing database performance in cPanel. Learn expert tips on tuning MySQL 8 and MariaDB settings to reduce load times and enhance efficiency.<\/p>\n<\/div>\n

<\/i> Test first:<\/h3>\n

The settings below are examples. The right values depend on your server’s memory and workload, so change one thing at a time and test on a copy of the site.<\/p>\n<\/div>\n

Short answer:<\/strong> Most slow databases on hosting accounts are caused by a few slow queries, missing indexes, bloated tables such as WordPress autoloaded options, and no caching. As a cPanel user, clean up the database, add an object cache such as Redis, and keep plugins lean. As a server administrator, size innodb_buffer_pool_size<\/code> for your RAM, turn on the slow query log, and fix the queries it shows. MySQL 8 no longer has a query cache, so do not try to enable one.<\/div>\n

<\/i> Find out whether the database is the problem<\/h2>\n

Before tuning anything, confirm the database is what makes pages slow. A query monitor plugin (on WordPress, Query Monitor) shows how many queries each page runs and which are slow. Hundreds of queries per page, or single queries that take more than a second, point to the database.<\/p>\n
