I have not done any tests lately that would reveal the speed of each of the new upcoming browsers. The latest official builds have been tested, they are at the time of the test: Opera 9.5 build 9815/1834, Firefox 3 Gran Paradiso beta 4 and Internet Explorer 8 beta 1. I have been using the Webwait application for this test which monitors page loading times of pages that you select.
