FireFox 4 beta faster than Chrome

  For the first time javascript engine in Firefox 4 beta 8 builds clocked faster then google chrome's V8 engine. Mozilla’s “Are We fast Yet?” charts are showing the combined Firefox TraceMonkey and JaegerMonkey build to be faster than Chrome in Webkit’s Sunspider test.

  "JaegerMonkey" is the code-name for a new javascript engine, It is a JIT compiler for Javascript. TraceMonkey is the original javascript engine that is introduced in FireFox 3.5 . JagerMonkey is a general-purpose compiler which converts entire methods to machine code. When it detects a loop that can be traced, it automatically engages the trace compiler, which makes it even faster. Mozilla is optimizing the combination of  Jaeger and Trace working together in Firefox4 to get the best of Tracing and JIT.
