I accidentally left out the telco benchmark, which is bad since cdecimal makes it just scream on Python 3.3 (and I verified with Python 3.2 that this is an actual speedup and not some silly screw-up like I initially had with spectral_norm):

You could also make the pickle benchmark use the C accelerator module by passing the --use_cpickle flag. The Python 3 version should be a lot faster.

perf.py already uses --use_cpickle:

Running fastpickle...
INFO:root:Running ../cpython/builds/3.3/bin/python3.3 performance/bm_pickle.py -n 5 --use_cpickle pickle
INFO:root:Running ../cpython/builds/2.7-wide/bin/python performance/bm_pickle.py -n 5 --use_cpickle pickle

One thing that might make a change is using -1 for the protocol instead of 2, but that means losing the perk of perf.py doing all of the calculations, etc.
