Speed test: Google Chrome beats Firefox, IE, Safari

Google's Chrome trounces Firefox, Internet Explorer, and Safari on speed tests for JavaScript, a key foundation for rich Web apps. But Google picked the benchmarks.

Google introduced Chrome in part because it wants faster browsing and the richer Web applications that speed will unlock. So how does Chrome actually stack up?

Lars Bak, the Google engineer who was the technical leader for Chrome's V8 JavaScript engine, said at the launch event Tuesday he's confident Chrome is "many times faster" than the rivals at running JavaScript, the programming language that powers Google Docs, Gmail, and many other Web applications.

But when pressed for specifics, he told me to try them out. So I did.

Google offers a site with five JavaScript benchmarks. On each one of these tests, Chrome clearly trounced the competition. I hope benchmarking experts and developers will weigh in with comments about how well these tests represent true JavaScript performance on the Web--either for ordinary sites or for rich Web apps.

Here's the site description of the speed tests:

• Richards: OS kernel simulation benchmark, originally written in BCPL by Martin Richards (539 lines).

• DeltaBlue: One-way constraint solver, originally written in Smalltalk by John Maloney and Mario Wolczko (880 lines).

• Crypto: Encryption and decryption benchmark based on code by Tom Wu (1,689 lines).

• RayTrace: Ray tracer benchmark based on code by Adam Burmister (3,418 lines).

• EarleyBoyer: Classic Scheme benchmarks, translated to JavaScript by Florian Loitsch's Scheme2Js compiler (4,682 lines).

A few notes: First, your mileage may vary; I ran these tests on my dual-core Windows XP machine.

Second, my apologies here to Opera, whose browser I don't have installed.

Third, I tried to run the SunSpider benchmark tests as well, but perhaps because a lot of other curious people had the same idea on the day Chrome launched, I couldn't get to the site.
