If you don’t optimize your database you’ll find your site slowing down day by day. The reason for this is that WordPress stores post revisions in your MySQL Database tables every time you add content, edit posts and click the Save Draft button.
Here’s an example:
WordPress Post Revisions
If you take a look at the bottom of your Edit Post screen you’ll see what i mean. When i deleted my post revisions using the WP Optimize plugin, my database decreased in size from 97mg to 23mg.
Deleting post revisions will clean your database and make your database smaller and faster. You could do this manually using phpMyAdmin in cPanel or simply install a plugin like WP Optimize.
Caution: Always make sure you create a full database backup using phpMyAdmin before making any changes to your database.
