WebKit's SquirrelFish canes Tamarin

The next generation of Javascript interpreter for WebKit, called SquirrelFish, has been announced and is already beating the competition from Mozilla and Adobe's Tamarin project.

Graphs from Charles Ying's blog show SquirrelFish beating a vanilla Tamarin implementation by 1.9 times.
 
In the official announcement of SquirrelFish is a graph which shows an improvement of 1.6 times over WebKit's previous interpreter.
 
The performance boost comes from eliminating the interpreter's syntax tree and switching to bytecode. Full details can be found in the announcement and make sure you take your knowledge of compiler design with you.
 
Apparently this is just the beginning, which can only be good news for Safari and the iPhone. What are the odds that we'll see graphs touting the Safari's latest performance boost at an upcoming Apple conference?
 
You can experience the SquirrelFish in the latest WebKit nightly builds, although Windows is less optimised than other operating systems at the moment.
