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.
The static html files will be served to the vast majority of your users:
- Users who are not logged in.
- Users who have not left a comment on your blog.
- Or users who have not viewed a password protected post.
99% of your visitors will be served static html files. One cached file can be served thousands of times. Other visitors will be served custom cached files tailored to their visit. If they are logged in, or have left comments those details will be displayed and cached for them.
