I'd suggest trying the non-vectorized version on PyPy. This code seems very JIT-...

On my rMBP, I did a quick back of the envelope comparison using PyPy 2.2.1 vs CPython 2.7.6 on OS X Mavericks and came up with (best of 3 runs):

    $ time pypy testcode.py

    real    0m1.529s
    user    0m1.402s
    sys     0m0.121s

    $ time python testcode.py                                                                                            

    real    0m13.880s
    user    0m13.635s
    sys     0m0.241s

    $ time python testcode_vectorized.py 

    real    0m0.746s
    user    0m0.551s
    sys     0m0.139s
