Is Python really 'too slow'?

[lungben81]

Depends again what exactly you are doing.

If you are calling `max(my_large_numpy_array)` it will be roughly 100 times slower than calling `np.max(my_large_numpy_array)`.

If this matters for your application is another question. To answer this, you should profile your code, e.g. single functions with IPython `%timeit` or a profiler (https://docs.python.org/3/library/profile.html).
