A new experimental feature has been added to today’s Chromium build – “Web Page Prerendering.”
This feature prerenders complete webpages in the background for a faster browsing experience.
After you enable “Web Page Prerendering” from the “About:Flags” page, it will try to guess which page you are going to go next and will then pre-render the page and keep it ready for you in the background so that it loads faster than normal. [via Chrome Story]
