Works well, good documentation, and fantastic support responses

If your host is using Litespeed, then it would be ridiculous not to choose this plugin for all your caching and optimization needs. First, the plugin works great and it’s easy to verify that with the various page speed tools. What impresses me most though is the excellent support responses, both for caching newbies and experts who just need the setup details. The backend explains all the options well and there is more to read on the wiki and great blog articles if that’s not enough. And, to their credit, the developers respond quickly to bug reports and feature enhancements on every channel. I’ve submitted several requests so far and the majority of them are already implemented (in a matter of just a couple weeks). This is how plugins should be.
