I wanted to find a graphic or image for this post, but none are applicable. This is because WP Super Cache, an essential plugin for WordPress users, does its work completely behind the scenes. How exactly does it make your blog faster? I’ll let the designers explain:
WP Super Cache is a static caching plugin for WordPress. It generates html files that are served directly by Apache without processing comparatively heavy PHP scripts. By using this plugin you will speed up your WordPress blog significantly.
This plugin is a fork of the excellent WP-Cache 2 by Ricardo Galli Granada. WP-Cache 2 caches the pages of your WordPress blog and delivers them without accessing the database. Unfortunately it still means loading the PHP engine to serve the cached files.
WP Super Cache gets around that. When it is installed, html files are generated and they are served without ever invoking a single line of PHP. How fast can your site serve graphic files? That’s (almost) as fast it will be able to serve these cached files. If your site is struggling to cope with the daily number of visitors, or if your site appears on Digg.com, Slashdot or any other popular site then this plugin is for you.
A vast majority of visitors to your blog will be anonymous surfers who don’t log in and don’t leave comments. These are the people who will benefit form WP Super Cache, and in all likelihood, they won’t even know it. But given the choice between a lightning-fast page and a slower page, most visitors will be far more willing to return to the more efficient site.
On top of that, if your site pulls in so much traffic that it’s affecting page load times, WP Super Cache will ease that stress. To download this useful plugin or donate to its creators, visit the WP Super Cache home page.
