DATABASE OPTIMIZATION

You can also optimize your databases via the following steps :

      Login to cPanel
      Click on the phpMyAdmin button in the Databases section.
      Select the database you want to optimize from the list in the left column, which  should take you to the "structure" tab for the database.
      Select the tables you wish to optimize by checking the check box in front of each one, or clicking on Select All if you want to optimize all of them. 
      On the drop down box that says "with selected..." select "Optimize Table."  This will optimize the table and take you to a new screen.
