Firefox vs Opera Mobile javascript performance on the N9

I’m quite pleased with the N9′s built-in web browser performance but some might think it’s a little light on the features, options or customizations.

Recently, two new competing web browsers became available for free at the Nokia Store for the N9:

- Mozilla Firefox v10.0.2

- Opera Mobile Labs v11.50.21

While both of them offer plenty more features than the stock webkit-based web browser, my main concern was if any of them brought significant improvements on the javascript performance over the built-in one.

I’ve run the SunSpider javascript benchmark on both browsers and below you can see the results Firefox and Opera,¬†respectively, achieved.

As you can see, Firefox did it in 3284.8 ms and Opera completed the same test in 5772.3 ms.

Opera took substantially more time than Firefox doing the same benchmark, so it definitely has a lot of room for improvement on future updates.

The Firefox result is quite good, but not that impressive, since it’s more or less the same result the stock browser already achieved. As you can see in a previous blog post, the stock browser made it in 3466.6 ms which is only slightly slower than the Firefox one. Maybe Firefox 11, already launched on Android, comes with javascript performance enhancements that will allow it to become significantly faster than the stock browser.

N9′s PR1.2 firmware update is expected to arrive soon, so let’s see if the stock browser also gets some performance improvements.
