Google Chrome_ulti fast new Browser frm GOOGLE

Google Chrome is a web browser built with open source code and developed by Google. The name is derived from the graphical user interface frame, or "chrome", of web browsers. Chromium is the name of the open source project behind Google Chrome, released under the BSD license.It is feature-complete compared to Chrome, but the user interface is less polished. By releasing the underlying technology as open source, Google may be aiming for an overall improvement in browser performance; forcing all browsers to provide the kind of fast and reliable platform Google needs for its web applications.

Speed

The JavaScript virtual machine was considered a sufficiently important project to be split off (as was Adobe/Mozilla's Tamarin) and handled by a separate team in Denmark. Existing implementations were designed "for small programs, where the performance and interactivity of the system weren't that important", but web applications such as Gmail "are using the web browser to the fullest when it comes to DOM manipulations and Javascript". The resulting V8 JavaScript engine has features such as hidden class transitions, dynamic code generation, and precise garbage collection.Tests by Google show that V8 is about twice as fast as Firefox 3 and the Safari 4 beta.

Several websites have performed benchmark tests using the SunSpider JavaScript Benchmarktool as well as Google's own set of computationally intense benchmarks, which includes ray tracing and constraint solving. They unanimously report that Chrome performs much faster than all competitors against which it has been tested, including Safari, Firefox 3, Internet Explorer 7, and Internet Explorer 8. While Opera has not been compared to Chrome yet, in previous tests, it has been shown to be slightly slower than Firefox 3, which in turn, is slower than Chrome. Another blog post by Mozilla developer, Brendan Eich, comparing the Javascript engines in Firefox 3.1 and Chrome using the SunSpider test results, states that some tests are faster in one engine and some are faster in the other.^[39] John Resig, Mozilla's JavaScript evangelist, further commented on the performance of different browsers on Google's own suite, finding Chrome "decimating" other browsers, but he questions whether Google's suite is representative of real programs. He states that Firefox performs poorly on recursion intensive benchmarks, such as those of Google, because the Mozilla team has not implemented recursion-tracing yet.
