The latest versions of the five most major web browsers (Mozilla Firefox 3.5, Google Chrome 3.0, Microsoft Internet Explorer 8.0, Opera 10.0, and Apple Safari 4.0) went head to head under six performance indicators: JavaScript speed, average CPU usage under stress, DOM selection, CSS rendering speed, page load time, and browser cache performance. Each web browser was tested three times under an unprimed cache (except for the browser cache performance), and their average value reported in the results.
