The WordPress Super Cache plugin generates static html files from your dynamic WordPress blog. After a html file is generated the webserver will serve that file instead of processing the comparatively heavier and more expensive WordPress PHP scripts.
We strongly recommend that a cache plugin such as WP Cache be installed for busy WordPress sites. This will allow your website to handle more simultaneous visitors and also typically loads much faster than without the caching plugin.
WordPress Super Cache will be installed by default with all new Fantastico WordPress installations. If you or a client wants it to be removed, that user can simply deactivate it in their wp-admin/ directory.
