When we think about how to make a Drupal website load faster, we often focus on how to make Drupal render the pages faster: optimizing queries, caching entities, and so on. But out of the box Drupal has several layers of caching enabled by default, and many popular Drupal hosts have additional systems in place like memcached and Varnish to further enhance the overall page load. In practice, the load of the page itself is often a small fraction of the overall time and data needed for a visitor to view a page.
