Cool! For the client test I'm referring to, these would be long-lived clients that stay around and just TCP ping for an echo server, rather than HTTP calls that connect/disconnect.

In my experience, PyPy+twisted is around 5-25x faster CPython/twisted, and smoked asyncio as well. Would be great to see how uvloop compares there, and of course, someday when PyPy supports Python 3.5, there's no reason it couldn't use uvloop via cffi I'd hope.

Yep, I'm curious to see what will happen there. Do you have any suggestions on what tool to use to generate the load?

We'll figure that out! ;)

I wrote a tool to evaluate memory per connection one layer up (at websocket level), using autobahn. It works in asyncio, so it should work fine with uvloop.
