Drupal core performance.

• To contribute to the Drupal community of users, Webmasters, and developers,
presenting them with a practical book on how to keep Drupal sites running smoothly
and presenting practical tips on keeping sites maintained and updated
using core performance strategies.

• To target both beginners and advanced users of the Drupal framework/CMS. This
book provides practical tips and knowledge for novice Drupal users as well as
advanced Drupal developers.

• To help Drupal site Webmasters and developers keep their sites running fast and
well maintained.

Use Development module
• What do your recent log entries tell you?

• The Development (Devel) module:

The Devel module provides a suite of tools for the Drupal theme and performance
developer. Two major components of the Devel module include helper utilities that
monitor performance of your site, and tools for themers that allow for quick and
more accurate theme development.

In chapter 3 we look at how to use the Devel module to enhance performance on our
Drupal site. Both Drupal beginners and advanced developers will gain Development
module best practice tips from this chapter.

We’ll use the Devel module to check on database queries that occur during our page
loads and how long these queries take to run. We’ll use the Development block to
get easier access to some common performance tools such as cron, performance cache,
and theme registry.
