Now that Mozilla has released Firefox 11 it's time to update the Big Browser Benchmark, where we take the leading browsers and pit them against four of the toughest benchmark tests available to see which is the tortoise, and which is the hare.
Here are the browsers that will be run:
Internet Explorer 9 32-bit
Firefox 10 (left in the running for comparison with Firefox 11)
Hare: Chrome 17
Tortoise: IE9 32-bit
Firefox 11 is slightly slower than Firefox 10 in this test.
Little has changed since the last time I ran the Big Browser Benchmark because the only big change is that Mozilla has release Firefox 11. Overall, Firefox 11 offers about the same performance as Firefox 10. The biggest slip in performance is on the SunSpider benchmark test, where Firefox 11 has now slipped behind Opera 11. I found this quite interesting, so much so that I reran the test to make sure that there wasn't an anomaly.
That said, the gulf between Firefox 11 and Firefox 10 is small. Tiny in fact. Even on the SunSpider test, the difference between the two browser is a little over 10 milliseconds.
