Here is the IE Release Candidate 1 benchmarked against Opera 10 alpha, Firefox 3.1 beta 1, WebKit r40220 and Chrome 2.0.158.0 on the Sunspider JavaScript test. Please note that shorter bars are better.
Sunspider is regarded as the benchmark in JavaScript performance testing. Four months ago, we compared the major browsers using this test and the landscape is much the same.
IE8 still trails the opposition by an awful amount; removing Opera from the comparison would leave IE8 at almost three times slower than its nearest competitor.
