The WebKit's newest JavaScript engine SquirrelFish Extreme is available now. This claims to be twice as fast as its predecessor (i.e. SquirrelFish), 35% faster than Google Chrome's V8 and 55% faster than Mozilla's TraceMonkey.
The following comparison chart shows how good the SFX engine is.
SFX uses four different technologies to deliver much better performance than the original SquirrelFish:
1. Bytecode optimizations
2. Polymorphic inline caching
3. Context threaded JIT compiler
4. Regular expression JIT compiler
This blog post on WebKit website explains these technologies in detail.
