WP Super Cache is an available plugin for Wordpress installations to store cached versions of your dynamic PHP pages. Installing WP Super Cache can also reduce the number of compute cycles used by a site since it reduces the load on the cluster as well.
WP Super Cache is available at http://wordpress.org/extend/plugins/wp-super-cache and is included by default with the Wordpress One Click Install in the control panel.
To install WP Super Cache, follow the instructions provided for the plugin located here: http://wordpress.org/extend/plugins/wp-super-cache/installation/. If you have installed Wordpress via the Wordpress One Click Installer you already have Super Cache installed.
In addition to the instructions included with the manual, the following additional changes are recommend and have been tested and shown to increase the efficiency of WP Supercache in Cloud Sites.
Go to settings for SuperCache and click on the Advanced Tab.
Mark the following items:
After making those changes, click Update Status.
After the screen refreshes scroll down to the Mod Rewrite Rules section and click Update Mod_Rewrite Rules.
Scroll down to Expiry Time & Garbage Collection.
Change cache timeout to 0 seconds then click Change Expiration.
Click on the Preload Tab next.
Any time a layout change has been made such as adding a widget or changing the theme, it will be necessary to go to the admin panel and click delete cache, verify your page looks as you want, then go into into the Supercache settings, go to the preload tab and click Preload Cache Now to regenerate the cache for the site.
For security purposes and optimizations, it is important to keep the plugin (and Wordpress itself) up-to-date. This can be done through the Wordpress Dashboard.
