Databases can grow quite large, particularly on websites with a lot of content. In such cases, optimizing a database should help improve the performance of a site.
Optimizing MySQL database is important for many reasons, most importantly to boost up the rate in which your MySQL database displays results. Generally, optimization will yield more noticeable results the larger your database is (for example with over 7500 rows or if it’s over 350-500MB in size). The optimization part can be carried out using phpMyAdmin which is a free MySQL database management tool available with most hosting providers.
