Well for one, it'd be nice to be a little closer to comparing apples to
apples (how fast a VM can interpret and execute the bytecodes). Secondly,
I was very suprised that, with a JIT, Java was only meagerly faster than
Python.  I was expecting an order of magnitude faster for most stuff, so I
was curious to know how slow Java was without the JIT. Finally, even
though Java and Python are wildly different in many ways, knowing the
interpreted vs. JIT'ed speeds might give a little insight into the
potential benefits of a Python JIT.

If I was really really interested in the Python-Java debate I'd go do the
tests myself, but since I'm just sorta curious I was asking Bryan in the
hopes that he still had the tests setup and it'd be easy to re-run them.

Sure, why not?
