This plugin caches the whole output to static files and compresses them.
This project is specificated on speeding up your blog. With special techniques your blog will get speeded up very strong! But watch out, randomized content wouldn't be randomized, because the content is saved in static files, and the Admin-bar from the frontend will be removed! In the backend the plugin is strongly costumizable so you have total control of caching. You can define expiering times, so that the cachefile will be renewed in a certain interval. A secial feature is the "brutal mode". It starts a short script at the beginning of the programm, so the resouces your blog needs will be drasticaly reduced, if a cachefile exists.
