print("Elapsed (with compilation) = %s" % (end - start))

print("Elapsed (after compilation) = %s" % (end - start))

This, for example prints::

Elapsed (with compilation) = 0.33030009269714355
Elapsed (after compilation) = 6.67572021484375e-06
Elapsed (with compilation) = 0.33030009269714355s
Elapsed (after compilation) = 6.67572021484375e-06s

A good way to measure the impact Numba JIT has on your code is to time execution
using the `timeit <https://docs.python.org/3/library/timeit.html>`_ module
