JavaScript performance improvements coming for Firefox 3.1

Mike Shaver writes, “Over the past year, JavaScript performance on the Web has undergone a striking revolution. Virtually every browser has improved its engine to produce significant gains in execution speed; Firefox 3 is about 3 times faster than Firefox 2 in various JavaScript benchmarks, for example. We’re not done. In addition to continuing to work on our existing JavaScript interpreter, we’re also looking farther into the future of JS performance. Yesterday we landed TraceMonkey in the Firefox 3.1 development tree, configured off by default. We have bugs to fix, and enormous number of optimizations still to choose from, but we’re charging full speed ahead on the work we need to do for this to be part of Firefox 3.1″. Early tests are showing significant speed and performance improvements, and all of this has been blogged about at length by the various people involved:
