While I'm somewhat loathe to help you guys go faster (that whole pie thing) you might want to take a look at commonly used pairs of opcodes and reordering the code in the switch body so pairs are adjacent and more likely to be in cache.

I caught the whole pie conversation, but I missed how you were going to test Parrot against Python.

How exactly will this competion be measured?
