Seems there could be a cost/benefit analysis here. Ten times faster than python might be sufficient for some applications given the potential for much faster deployment, regardless of whether handwritten C might be faster.

You're absolutely right: you don't necessarily need to be within 10% of pure C++ if algo development is made far easier by using python/numpy. But it would be good to have a hand-written C++ baseline to determine where the cost/benefit point is (at least for this example).
