Introduction

Since the time our first Web Browser Grand Prix debuted, the already-raging browser wars have become heated indeed. In case you haven't been keeping tabs on the browser news, let's begin by getting up to speed on the latest:

Once again, we find ourselves in a situation where multiple parties are claiming the speed crown. Obviously, all of these claims can't be true. The fact is, it's easy enough to produce favorable results supporting ANY browser. You can even do this for IE6 if you try hard enough. Simply pick a single benchmark or a group of potato-oriented tests and viola, there's the fastest browser ever! That is why we run all of them. If we find a valid benchmark that runs on every browser, we use it.

While this is a follow-up to our original Web Browser Grand Prix, we have also included some standards compliance testing along with enhanced memory benchmarks. We feel that even though these tests do not directly affect speed, they are crucial to overall performance. But don't worry, we'll separate those benchmarks from our speed tests in the conclusion, so you'll still get to find out which Web browser is the fastest when judged purely on raw speed. Without further adieu, let's get to the testing!
