Upcoming Browser JavaScript Engine Benchmarks
Internet Explorer 7 scores an abysmal 90522ms. (...) IE8-beta2 scored at 9542ms. But, for reference, in the same virtual environment Firefox "Minefield" was still able to pull off 1873ms. So, as while still no where near as fast as the other guys, IE8 is lightyears ahead of IE7 in its javascript performance.
