Any idea why x.fillna(0.) is so much more expensive than x.dot(y)?

For some functions where fillna(0.) has a different result to skipna=True, I could see it being worthwhile to writing new routines. But for dot product, it's definitionally the same. And fillna seems a much simpler operation than dot...
