The only untouched methods are the ones related to morphology. Everything else is much faster.
I can't get pad to be faster then NumPy's. I'm 95% convinced that it's impossible with ndarray 0.15.x. Just copying the input into the padded center region takes longer than the complete job in NumPy.
Even so, pad is a lot faster than it was. Depending in the mode, I'm 50%-400% faster.
Correlate is also faster. It was automatically optimized by pad and I made one loop faster and I used unsafe in the other loops. I think we're around 25% faster. And we're faster than SciPy for some inputs and args.
See #4. This MR doesn't fix the issue but we're much better now!
