Test Your Browser’s JavaScript Performance

Cnet ran some tests on the JavaScript performance of selected browsers like the latest Firefox version, Firefox beta and Google Chrome builds. JavaScript performance was in the news since Google and the Mozilla Firefox development team announced improvements in JavaScript performance.

Cnet used the SunSpider JavaScript Benchmark to test browser performance of the browsers. There are other factors that have an impact on JavaScript performance like the processing power of the computer system.

The results were that the latest Firefox 3.1 beta with the new JavaScript engine TraceMonkey was the fastest with a score of 2,257, followed by Chrome with 2,904, Firefox 3 beta 1 without TraceMonkey with 4,233, Safari 3.1.2 with 6,351 and Internet Explorer 8 Beta 2 at the end with a score of 9,025.

Cnet failed to test any version of Opera and should probably have tested the latest nightly test of Safari instead. Here are the results that a Windows XP service pack 3 with a Intel 8400 Wolfdale processor and 4 Gigabytes of computer memory.

• Firefox 3.1 Beta 1 without TraceMonkey- 1800
• Firefox 3.1 Beta 1 with Tracemonkey 1817
• Firefox 3.03 – 2139
• Opera 9.6 – 2736

It’s a bit surprising that Firefox without TraceMonkey was faster than Firefox with it enabled. It could be due to the fact that the portable version of Firefox has been used to run the tests. But the interesting question is, how does your browser compare? You need to run at least two browsers to be able to tell how it compares to the other browser.

Keep in mind that JavaScript performance is not everything and that page loading time is dependent on additional factors.
