body: <p>I have a wordpress site with below plugins:</p>
  
  <ul>
  <li>wp-types</li>
  <li>seo by yost</li>
  </ul>
  
  <p>I have only 21000 post from my custom post type but my database size is 353 MB.</p>
  
  <p>My biggest table is:</p>
  
  <ul>
  <li>post table: 21165 Records => 189.6 MB</li>
  <li>post meta table: 199593 Records => 120.6 MB</li>
