<p>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.</p>
<p>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>.</p>
<p>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.</p>
<p>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>. Take a look at the wiki for <a href="https://github.com/pantheon-systems/wp-redis/wiki" rel="nofollow ugc">useful code snippets and other tips</a>.</p>

Do a little dance

Works like a charm and significantly improves the page rendering speed for my website. Play nice with https://wordpress.org/plugins/batcache/. These two allow me to get literally light speed performance for static pages.

Works like a charm!

Back your WP Object Cache with Redis, a high-performance in-memory storage backend.

Cache Warmer


Developer is helpful and responsive.If you have a sitemap, click the option for this, set depth to 1, decide your update interval (match it to the default cache expiration time) and you're good to go.I use this alongside NGINX page caching and Redis object caching.


Does the job!


I have been looking for a plugin like this for a long time. With Redis full page caching, they are only added to the cache on first load and then dropped after 4 hours in the cache. This is a really nicely made plugin that will preload these files into cache at regular intervals. It's an amazing plugin.


Perfect plugin

Visits website pages to warm (create) the cache if you have any caching solutions configured.
