IE9 vs. Chrome 8.0, Firefox 4.0, Opera 10.6, Safari 5.0 – Performance Smackdown


The latest development milestone of Internet Explorer 9 released at PDC 2010 is almost three times as fast as the first preview of the browser introduced just a year ago at PDC 2009, in terms of the WebKit SunSpider version 0.9.1 JavaScript Benchmark.

IE9 Platform Preview #6 wraps up SunSpider in 292 ms, and is the fourth fastest browser according to Microsoft’s test, outran only by Chrome 7 (7.0.517.41) with 257 ms, Opera 10.6.1 with 246 ms and Chrome 8 Nightly (8.0.552.11) with 241 ms.

Customers will be able to see via the graphic included below that IE9 PP6 manages to outperform releases such as Firefox 4.0 Beta 6, and Safari 5.0.2 in terms of JS performance.

But at the same time, users must understand that JavaScript speed is not synonymous with overall browser performance.

“Platform Preview 6 continues improvements to individual sub-systems, like the JavaScript engine. One measure of JavaScript performance is the Webkit Sunspider microbenchmark.

“The differences between browsers on this microbenchmark are converging within thousandths of seconds on tests that repeat operations many, many times to find any differences at all,” revealed Dean Hachamovitch, Corporate Vice President, Internet Explorer.
