Cache by Folium

Fast, easy to use cache for WordPress with option for up-to 3 separate CDN's - for js, css & images from 3 providers. Added the ability to set and forget Database clean-ups on a scheduled timescale including removing revisions, clean-up transients, remove comment spam. Generally help keep the Database lean and tidy. Built in support for GridPane based WordPress Installations with more functionality coming soon. Added Automatic CDN support, Free for now, just enable in settings and your site will be automatically added to the grid. We have many features planned and have an active development cycle which will be user focused based on feedback. For extra performance we recommend Featherweight, our request cleanup plugin for reducing front-end weight and removing unused WordPress output. Coming Soon – Dedicated WooCommerce caching for optimized e-commerce performance. For hands-on performance work, see Folium Studio.
