Overview
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 WordPress.org or Github.
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 e…

Best most lightweight Redis option for WordPress

Great plugin. I’m evaluating it now as a backend Redis cache. However, installation was not straightforward or clear. I wish it was automatic. However, the manual install requires copying a file manually. If you run multiple WordPress sites on a self-hosted install, you must also make sure to edit the object-cache.php file and add a cache salt key or you will get errors. Once these are resolved, it seems to be functioning well.
4 stars for the excellent plugin.
-1 for the difficult installation. I wish it were more straightforward.
