This document summarizes a presentation on Drupal caching and optimization strategies given at the Melbourne Drupal Mini-Conference on February 3rd, 2007. It introduces the presenter, Simon Roberts, and outlines reasons for optimizing a Drupal site, such as providing a better user experience through faster page loads, supporting more concurrent users, and requiring less hardware. The document also notes that performance and scalability are related but different, and lists some factors not covered in the presentation that also contribute to system performance, such as physical hardware, operating systems, databases, and software configurations.
