Drupal has been criticized as "being slow" and, it's true, performance can sometimes be an issue. Some performance improvements are made easily by turning on core caching and leveraging a good hosting platform that provides things like Varnish and Redis support. Once you get through the easier wins, tuning can get more challenging and, often, the issues lie with slow database queries. In this session, we will cover: Identifying slow database queries Manually running queries against a database Approaches for improving query performance Testing query changes for improvements Altering Views and non-Views queries Attendees will walk away with an understanding of how to find sluggish database queries and ways to make them faster. Intended Audience Anyone who develops Drupal sites and wants to make them faster would benefit from this session. Skill Levels This session is suitable for intermediate Drupalers as well as for advanced developers who have not done performance tuning for database queries.
