WordPress 静态缓存插件WP Super Cache，是 WordPress 官方开发人员开发的，支持中文，必备插件。
This plugin generates static html files from your dynamic WordPress blog. After a html file is generated your webserver will serve that file instead of processing the comparatively heavier and more expensive WordPress PHP scripts.
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.
