The video of Jim Hugunin's talk from MIX has a slide showing how many 
Pystones you get on some different versions of Python. Of course that is 
just one benchmark and not terribly relevant to any real applications, but 
if you do get a similar speedup in real code 'Python that runs on 
steroids' won't be far from the truth.

The claimed figures were 50,000 Pystones for CPython 2.5, and 101,000 for 
the latest IronPython. (He didn't mention it, but I believe Psyco will 
outdo both of these.)
