Mozilla: TraceMonkey Project

Tej kohli had already various topic related to Mozila updates and its version . Now Tej kohli comes with Mozila new TraceMonkey Project which make its more faster and less panic.

"TraceMonkey is a project to bring native code speed to JavaScript," said Mike Shaver, Mozilla's interim vice president of engineering, adding that JavaScript performance nearly doubles compared to Firefox 3.0, based on the SunSpider test of JavaScript performance. That speeds up many basic tasks, but it also brings image editing and 3D graphics into JavaScript's abilities, he said.

Now world will be experienced with faster Mozila web application which became true because of its new JavaScript Engine. TraceMonkey is just a new JavaScript just-in-time compiler which able to enhance feature like faster JavaScript execution. It aims to put JavaScript on a par with natively-compiled code so that certain applications cease to be as sluggish as they have been historically.
Mike Shaver Mozila vice president Mike Shaver said that “Developer and user demand for performance is insatiable, and at Mozilla we demand it ourselves, since our application itself is largely and increasingly written in JavaScript. In addition to improving the performance of web applications, our work on JS performance in Firefox 3 made our own application snappier and more responsive,” “We’re not done. In addition to continuing to work on our existing JavaScript interpreter (some 20% improved over Firefox 3 already), we’re also looking farther into the future of JS performance, and have some early news to share.”
While TraceMonkey was tested than its be found that Javascript function work much faster as compared with Mozila 3.0 . More specifically its cites 22.2x increases on function call over Firefox 3, a 37.5x increase in performance when it comes to global loops and a 20.8x increase in terms of closed loop performance. Moreover its takes advantages of a UC Irvine-developed technique called ‘trace trees’ as well as building on contributions and code that have been shared with the Tamarin Tracing project.
“The goal of the TraceMonkey project — which is still in its early stages — is to take JavaScript performance to another level, where instead of competing against other interpreters, we start to compete against native code. Even with this very, very early version we’re already seeing some promising results.”
Currently TraceMonkey is available in Alpha version of Firefox 3.1 and officials sources singing it might take end of the year for final release. While had giving the faculty to be turned off default , Mozilla has admitted that there are still “bugs to fix and an enormous number of optimisations still to choose from” before the leap from alpha to full-blown release can be made.
In separate news, users of Firefox 2.0 will now receive a prompt suggesting they upgrade to the latest version of the browser, according to a blog post by Mike Beltzner, the company’s director of user experience.
