In this chapter, we will learn how to optimize Drupal to improve its performance and speed. There are few steps through which we can improve the performance of the website.
Following are some of the ways to optimize the website.
Enable Cache blocks and Cache pages for Anonymous Users. Page caching lets your contents store in different database cache tables. Page cache is stored in the HTML content. It optimizes the page load time for anonymous users.
Step 1 − Click Configuration from the menu bar.
Step 2 − In Development section click Performance.
Step 3 − Enable Cache blocks and Cache pages for Anonymous Users by checking both the boxes. Then, click Save Configuration.
If you have many CSS files, it can lower your websites speed. Compress them by enabling Aggregate and Compress CSS files.
Enable this setting from AdministrationConfiguration→Development→Performance section. Drupal decreases the number and size of your CSS files.
Java files can also affect the performance and speed of your website. To compress this enable the Aggregate JavaScript files from the Administration→Configuration→Development→Performance in the bandwidth optimization section.
This decreases the number of requests that a shared hosting handles. Use CDN (Content Delivery Network) that hosts your media files and static files. CDN acts as an external cache for your files and will store them in high performance servers so that it is optimized.
Do not have many images which consume more space as this leads to slow website. Always resize your images and have few that are related to your website.
Optimizing themes is a very important aspect. Media files like high quality images, videos, audios and flash can affect your website and slow down the speed resulting in low performance. Try reducing the size and number of media files or maybe you can avoid using flash.

Drupal uses _drupal_exception_handler ($exception) function to handle the errors on the site. These errors will not be enclosed in a try/catch block. The script won't execute the function when an exception handler exits.
The code for _drupal_exception_handler is as follows −
function _drupal_exception_handler($exception) {
   require_once DRUPAL_ROOT . '/includes/errors.inc';
   try {
      // display the error message in the log and return the error messages to the user
      _drupal_log_error(_drupal_decode_exception($exception), TRUE);
   }
   catch (Exception $excp2) {
      // Another uncaught exception was thrown while handling the first one.
      // If we are displaying errors, then do so with no possibility of 
         a further uncaught exception being thrown.
         
      if (error_displayable()) {
         print '<h1>Additional uncaught exception thrown while handling exception.</h1>';
         print '<h2>Original</h2> <p>'. _drupal_render_exception_safe($exception).'</p>';
         print '<h2>Additional</h2> <p>'. _drupal_render_exception_safe($excp2).'</p><hr/>';
      }
   }
}
The function must be used on every Drupal request. This function is present at the line 2328 in the file includes/bootstrap.inc.
