Hyper Cache

Hyper Cache is a cache plugin specifically written to get the maximum speed for your WordPress blog.

It can be used in low resources hosting as well on high end servers.

Hyper Cache is purely PHP and works on every blog: no complex configurations are needed and when you deactivate it no stale settings are left around.

NOTE

Mobile detection server side and serving different content to mobile and desktop device is now obsolete.
Every modern WP theme deals with mobile/desktop contexts using the media queries, progressive enhancement and so on.
So I don’t see the need to keep the mobile/desktop cache separation and all the overhead in the plugin. The feature will be removed as version 3.5.

Short list of features:

• Mobile aware: double cache for desktop and mobile site versions
• HTTPS ready
• Mobile theme switch option: change the theme on mobile device detection
• Able to serve expired pages to bots to increase the perceived blog speed by bots
• Manages compression even on the fly for non cached pages
• Lots of configurable bypasses: matching cookies, matching urls, user agents, …
• Comments aware: is able to serve cached pages even to visitors who commented the blog (perfect for blog with great readers paritipation)
• Cache folder can be moved outside your blog space to exclude it from backups
• Controls over cache cleaning on blog events (post edited, comments, …)
• Autoclean to controls the cache used disk space
• CDN support
• Other special options
• Response header signature to check the working status
• bbPress specific integration

More can be read on the Hyper Cache official page.

You can further optimize the blog installing Autoptimize which cleans up the HTML, minifies and concatenates CSS and JavaScript.
