For sites concerned with high traffic, speed for logged-in users, or dynamic pageloads, a high-speed and persistent object cache is a must. You also need something that can scale across multiple instances of your application, so using local file caches or APC are out.
Redis is a great answer, and one we bundle on the Pantheon platform. This is our plugin for integrating with the cache, but you can use it on any self-hosted WordPress site if you have Redis. Install from <a href="https://wordpress.org/plugins/wp-redis/" rel="ugc">WordPress.org</a> or <a href="https://github.com/pantheon-systems/wp-redis" rel="nofollow ugc">Github</a>.
It’s important to note that a persistent object cache isn’t a panacea – a page load with 2,000 Redis calls can be 2 full seconds of object cache transactions. Make sure you use the object cache wisely: keep to a sensible number of keys, don’t store a huge amount of data on each key, and avoid stampeding frontend writes and deletes.
Go forth and make awesome! And, once you’ve built something great, <a href="https://github.com/pantheon-systems/wp-redis/issues" rel="nofollow ugc">send us feature requests (or bug reports)</a>.
