Mozilla was one of the first browsers to talk about native code compilation for JavaScript. In fact, this is what allowed Firefox and Chrome to zoom ahead of other browsers in terms of rendering speed. However, now that other browsers have also implemented similar features, Firefox has once again fallen behind.
Obviously, Mozilla isn’t pleased with the current situation. In most speed tests, current builds of Firefox end up getting trashed by every browser other than Internet Explorer. This has prompted Mozilla to begin work on a new engine called JaegerMonkey.
TraceMonkey
Work on JaegerMonkey is just getting started and it will possibly take several months for this to appear even in the alpha builds of Firefox. Nevertheless, this gives Firefox users something to look forward to.
