Jacob Gube has posted a handy chart over at Six Revisions titled "Performance Comparison of Major Web Browsers." He tests the current versions of five browsers:
- Mozilla Firefox 3.5
- Google Chrome 3.0
- Microsoft Internet Explorer 8.0
- Opera 10.0
- Apple Safari 4.0
In his tests he used the following performance indicators, tested three times each with an unprimed cache, and averaged the results:
- JavaScript speed
- average CPU usage under stress
- DOM selection
- CSS rendering speed
- page load time
- browser cache performance
When Google Chrome 3 was released in September, Google claimed a 150% increase in JavaScript performance from its previous version but didn't offer comparisons to other browsers. Opera also made improvement claims in its September release of Opera version 10, specifically a "40% faster engine." Those claims are also not made in comparison to other browsers. The overall performance ranking he assigns to the browsers isn't too much of a surprise, with Google Chrome as the best and Internet Explorer 8 as the worst. If he ran as many persistent tabs in Firefox as I do, it might not hold on to the #2 slot so easily. The ranking:
- Google Chrome 3.0
- Mozilla Firefox 3.5 (tied with Safari)
- Safari (tied with Firefox)
- Apple Safari 4.0
- Microsoft Internet Explorer 8.0
