DrupalCon Barcelona 2015: How Drupal 8 builds your pages?

This talk explores the inner workings of a Drupal 8 website when it receives an HTTP request. The speaker explains how Drupal identifies the appropriate code to execute, differentiates between cached content and dynamically generated elements, and examines the database queries that are triggered. By utilizing the Webprofiler module, attendees will learn how to analyze the page construction process, including the roles of stack middleware, routing components, and the Twig templating engine. The session emphasizes performance considerations such as memory usage, response time, and caching strategies, making it beneficial for both contributors and those simply curious about Drupal 8's architecture.
