Downsize CPU & DB usage in wordpress

Sagive,

  1. wp-blog-header.php loaded in the index.php on each page request. AJAX calls included (if that’s what you mean “time after time”.
    Then it loads template-loader.php.
  2. This has nothing to do with the SQLs you see, and not with the “spikes”.
  3. Install the Query Monitor plugin to see your SQLs better in the Debug Bar.
  4. Do not publish sensitive information here (like the name of your client in the first SQL). 🙂
