So it makes sense that Firefox 3.5 called its rendering engine TraceMonkey, and with it has made the browser more than twice as fast as Firefox 3, by our own measurements. Using the SunSpider Javascript benchmark tool on a Windows PC, Firefox 3.5 scored 1,426ms, which is significantly faster than Firefox 3 which scored 3,250ms. Safari 4 and Chrome 2 scored 910ms and 709ms respectively. The average user will not find the previous version slow, and so may not notice version 3.5 working much harder. But it is, and pages are loading closer to the speed of Chrome now.
