Why is numba faster than numpy here?

Question

I can\'t figure out why numba is beating numpy here (over 3x). Did I make some fundamental error in how I am benchmarking here? Seems like the perfect situation for numpy,

Answer 1

Numba is generally faster than Numpy and even Cython (at least on Linux).

Here's a plot (stolen from Numba vs. Cython: Take 2):

In this benchmark, pairwise distances have been computed, so this may depend on the algorithm.

Note that this may be different on other Platforms, see this for Winpython (From WinPython Cython tutorial):
