Firefox 3.5's Benchmark Scores Brutalize IE 8, Almost Tie Chrome

Tests were run on a robust desktop installed with Vista SP1, 4 GB of memory and Intel Core Duo E7200 2.53GHz processors.

The Peacekeeper benchmark test puts a browser through its paces by checking JavaScript functionality via a variety of features, among them: rendering HTML elements, performance in social networking sites and testing complex graphics. This is how each browser fared, (the higher the score, the better):

Chrome: 2747

Firefox 3.5:1843

IE 8: 675

SunSpider is another benchmark test that looks at core JavaScript functionality only. In this test, because the scores are in milliseconds, the lower the score, the better:

Chrome: 924.2 ms

Firefox 3.5: 1517.4 ms

IE 8: 8131.8 ms

Finally, we loaded in each browser one of our favorite sites for testing how a browser can handle serious graphics: www.papervision3d. It was amazing how much faster Firefox 3.5 loads this graphics-heavy site than in previous versions of Firefox. Firefox fully loaded the site in 10 seconds. Compare that to the 25 seconds it took Firefox 3.1 to load the same site and the 45 seconds it took to load the site with Firefox 3.

In comparison, Google Chrome essentially tied with Firefox 3.5, taking 12 seconds to load papervision3d.org. IE 8 was right on par with Firefox in this case, taking about 10 seconds to fully load. Mozilla's mantra with Firefox releases is "Fast, Faster, Fastest." That certainly seems to be the case according to test results, with each subsequent release outperforming the last.
