Webkit r47948 with Snow Leopard SunSpider Benchmarks

Last year October WebKit was the undisputed leader when it came to running the SunSpider benchmark. How does it compare with the latest nightly build of WebKit under Snow Leopard?

So, with all hardware remaining the same, the only changes are Snow Leopard and the WebKit build. I've gone from 745ms to 411.6ms. That's a speed bump of 1.8x. Not bad at all!
