Using Cython means you don't/can't use Pypy? Was that something you considered, e.g. with psycopg2cffi or a pure-python driver? It seems to be the defacto performant runtime for Python, and since performance is something you guys obviously care a lot about, I'm surprised it hasn't been mentioned in this thread.

Very excited to try out your code - thanks for sharing it.

A pure-Python implementation would probably never reach this level of performance, even under PyPy. Cython really makes it possible to basically drop down to C and write very efficient code.

That said, once PyPy supports 3.5, we will consider making a CFFI binding.

By using python asyncio, you can't use pypy because pypy doesn't support 3.5 yet (or probably for a while), so by going async, you are eliminating pypy right there.
