Why is chrome so fast?

I was reading this article and Chrome seems to be way ahead of the pack. But why is it so good? It's only been around for about a year but it's much better than any of the others.

Can anyo开发者_如何学Pythonne shed any technical light on this?

"We've often been asked what makes Google Chrome so fast -- from its snappy start-up time and fast page-loading, to the ability to run complex web applications quickly. To walk through some of the thought processes and technical decisions involved in making Google Chrome a fast browser, we've put together three technical interviews on DNS pre-resolution, the V8 JavaScript engine, and DOM bindings. In a future post, we'll also cover other important areas like WebKit and UI responsiveness." via http://blog.chromium.org/2009/12/technically-speaking-what-makes-google.html

"It's only been around for a year", and that's the point. It's brand new and shiney, uncluttered with legacy code, outmoded assumptions and general bloatware. It's pretty slim on actual features too. Also, google have had an awful lot of money and motivation to throw around recently, compared to the impovirished mozilla, and the tired old guardians of IE.
