Performance improvements coming for Firefox 3.1

September 15, 2008

Mozilla announced a new component in Firefox that will significantly speed up the browser’s JavaScript performance (available in Firefox 3.1 alpha-stage built).

Called TraceMonkey, the component is a Just-In-Time (JIT) JavaScript compiler that will eventually replace Firefox’s current SpiderMonkey JavaScript compiler. The new compiler can improve JavaScript performance by up to a factor of seven, and with more speed improvements down the road. For Mozilla JavaScript is increasingly important, not only because of more-demanding sites, but because much of the Firefox browser itself is coded in JavaScript.
