Web Browser Grand Prix 2: The Top 5 Tested And Ranked

Benchmark Results: JavaScript

SunSpider v0.9.1

Opera is the clear winner in the latest version of WebKit's SunSpider JavaScript benchmark. Trailing by one hundred milliseconds is Chrome, with Safari close behind in third. Fourth place finisher Firefox is nearly three times slower than the top three, while IE8 is just completely off the charts, taking more than five times longer to finish than Mozilla.

Google V8 Benchmark v5

As we might have predicted, Google Chrome scores the most points in the company's V8 benchmark. Opera comes in 450 points behind Chrome's score, while third-place finisher Safari trails the leader by over one thousand points. Firefox earns just shy of 300 points. Again in last place, IE8 receives a score of slightly over sixty.


The placing in JSBenchmark closely resembles that of the Google V8 test. Chrome again places first by a significant margin, but this time Apple's Safari slightly edges out Opera for second place. Firefox fills fourth place with IE8 floundering behind in fifth.

Mozilla Dromaeo JavaScript

Once again, Opera displays troubling results. It is simply too far ahead of the other contenders for this score to be valid. Chrome therefore becomes the winner here, with second-place Safari pulling in less than half the number of runs per second. Firefox takes fourth with just shy of sixty runs per second, while Internet Explorer scores fifty.

On a side note, Chrome v5.0.375.86 also displayed seriously skewed results in this test--almost a thousand more runs than Opera! However, the slight version change to 5.0.375.99 brought the outcome back in line with reality.

    July 7th - Firefox 4 beta released.
    Tom's impending road test STILL BEHIND THE TIMES
  • I agree. Firefox 4 was supposed to have the major speed up (especially in startup time.)
  • But you know what, apple said they have the world's fastest browser. I think we should just pack up and call it a day. The spoken word of god is indisputable...

    I'm very happy to see my beloved Firefox's performance.Whatever people say about Opera and Chrome, Firefox is the best IMO.And Apple is proved to be a liar from this article.

    I've been using Firefox for about to two years now. I can't get enough of adblock plus. One of my favorite plug-ins.
