The Plugin implements 2 things:

DNS-Prefetch

It looks for all CSS and JS Files which are loaded from external webpages and implement a dns-prefetch header tag.
This saves a lot of connection time on page load.

HTML5 Prefetch and Google Prerender

It makes a new table with small statistics and measures (internal) referal page to next page.
With these statistics, the most clicked “next” page will be automatically added as prerender. Prerender opens with very small CPU load the “next” guessed page already as a hidden Tab in the client browser. If the client select this page, the page can instantly showed without delay.
Tests have shown a pageload decrease of 68%.

Please note: The prerender needs some stats to work correctly. Don’t try to generate some statistic, wait few days / weeks and you have organic and true statistic.
