SquirrelFish Extreme
http://webkit.org/blog/214/introducing-squirrelfish-extreme/SquirrelFish Extreme as of today is nearly twice as fast as the original SquirrelFish, and over 10 times the speed you saw in Safari 3.0, less than a year ago. We are pretty pleased with this improvement, but we believe there is more performance still to come.
