The latest builds of the open-source Chromium browser, which you can download from this directory, are featuring a new Labs option that you can enable called Web Page Prerendering. You can get to the Labs menu in Chrome by entering “about:flags” into the Omnibox.
Enabling/disabling these in Labs is easier and faster than having to use command line switches, which is nice and means that some of these features are seriously being testing for a future release at some point.
Prerendering is clearly all about speed, which is of course Google’s mantra. Web pages will certainly load faster if they are capable of deciding which ones to pull data “speculatively” as noted in the screenshot above.
I assume this is all based on browser history, but at what point does Chrome start loading pages in the background? I tried looking in the Chromium revision reports, and found nothing. The only thing was an entry specifying this would be added to “about:flags” and that the feature itself would prove to be “wicked fast”.
Anybody have more details than that?
