New beta versions of Firefox and Google Chrome now are available, and in recent tests, CNet found Firefox the fastest, with Chrome right behind, in executing JavaScript, which powers applications such as Gmail and Google Docs.
The answer: both browsers made big strides, but Firefox still beats Chrome on one widely-used performance test, says Stephen Shankland. CNet writer.
When Chrome was released, Shankland ran Google's JavaScript speed test on Firefox 3.0.1, the initial Chrome beta, Internet Explorer 7 and 8 beta 2, and Safari 3.1.2.
He found Chrome led the speed test with an overall score of 1,851 and Firefox in second place at 205.
Running the same test on the latest developer version of Chrome, 0.3.154.3, boosted the browser's score to 2,265, a 22 percent increase. And Firefox jumped 15 percent to 235. Firefox 3.1 beta one, he says.
That test measures Firefox without its new TraceMonkey JavaScript engine enabled, though.
Faster execution matters for a couple of reasons. At some point, the browser will become the client for executing any number of consumer and enterprise applications that are not stored on a local hard drive. Speed will matter.
Also, users simply like faster-executing Web pages. Faster execution provides a higher end user experience.
