We already have a compiler that compiles what code it can to Java 
bytecode. That's helped performance substantially in a number of areas. 
We also have a very early, primitive implementaiton of YARV's bytecode 
engine. We're hoping that will provide a faster interpreted mode for 
JRuby, avoiding the AST walking we're doing now.
