Firefox's JavaScript to get a big speed boost

ARS Technica writes Mozilla is going to incorporate a new optimization technique in Firefox 3.1 that will greatly enhance the the performance of JavaScript:
I discussed this new optimization strategy with Mozilla's VP of engineering Mike Shaver and Mozilla CTO Brendan Eich, the creator of JavaScript. They are concerned that sophisticated web applications are being held back by the limitations of JavaScript interpreter performance. They aim to improve execution speed so that it is comparable to that of native code. This will redefine the boundaries of client-side performance and enable the development of a whole new generation of more computationally-intensive web applications.

They are "getting ready to take JavaScript performance into the next tier" with a radically innovative optimization tactic called tracing that has already produced performance improvements ranging between 20 and 40 times faster in some cases. They believe that this is just the beginning of what can be accomplished with tracing, and they expect to be able to achieve even better speed as the work continues.
