This article shows you how to use the database table optimization tool found in phpMyAdmin.
Over time, MySQL databases may become less efficient and run slower. It's very easy to optimize databases using the DB optimize tool found in phpMyAdmin. Using this tool is similar to defragmenting a computer, and can shrink a database's size and remove unused elements that are left behind from frequent changes, referred to as overhead. There is no danger in using this tool and you should consider running it occasionally, especially if your database changes frequently.
