For anyone who has ever encountered site performance issues, a caching solution is a must. Undoubtedly, WordPress’ object cache will be part of the solution; however, all too often, the effort involves installing a “magical” caching plugin without taking the time to really learn what the plugin is doing. In my talk, I want to reveal the magic behind these plugins by discussing what the WordPress object cache is. I will expose the brilliance of the object cache and discuss how it, along with a host of extensions for the object cache, is an essential component to a caching solution. I hope to shed light numerous facets of the WordPress object cache, including strategies for maximizing object caching, understanding persistent vs. non-persistent solutions, leveraging object cache extensions, and writing code for an object cached environment.
