Caching, Scaling, and What I've Learned Programming for WordPress.com VIP by Erick Hitter WordPress provides two great caching frameworks in its transient and object caching APIs. Used internally and available to developers, object caching can introduce many performance enhancements simply by activating a plugin such as Batcache or W3 Total Cache. But what about adding extra caching in a custom theme? Or building upon existing internal caching? Working on high-traffic sites both on the WordPress.com VIP platform and not, I’ve encountered these needs and implemented caching in some tricky situations. In this talk, I’ll demonstrate some of the interesting solutions devised to meet our clients’ needs and address issues related to scaling WordPress-powered sites. Erick Hitter is a web developer with Providence-based Oomph, Inc. specializing in complex WordPress implementations for high-traffic sites, including several on the WordPress.com VIP platform. He is also responsible for the company’s BuddyPress projects. Erick has created a number of WordPress plugins available from the official repository, including the Simple Facebook Share Button and Tag Dropdown Widget, as well as the WordPress.com VIP External Permalinks plugin.
