cache plugin like Borlabs Cache saves the dynamically generated content as a static file on your server’s storage. When the page is requested, this static file is loaded and send to the visitor, which is dramatically faster than the regular database requests. But that is not all. Your pages contain a lot of unnecessary whitespace or HTML-Comments, which only increase the overall size of the page, but are not important for your e.g. layout or design. Borlabs Cache removes all of them and uses GZIP to compress your page, which saves your and your visitor’s traffic.
