Cython + memoryviews isn't quite the right comparison here.

Right, tbc, I'm only referring to the top two lines of the pasted benchmark; i.e. once we enter python (even if only to access a numpy array) we're already losing a lot of the speed relative to the loop staying in C / Cython. So even if xarray were a python front-end to a C++ library, it still wouldn't be competitive if performance were paramount. ...unless pypy sped that up; I'd be v interested to see.
