Since this is a benchmark of eventloop based frameworks, it makes sense to only spawn a single eventloop and test against that. I looked through the code for the python servers and they are all configured for a single event loop, making this a comparison on equal footing.

Yes it's true you normally run multiple node processes in production, but you likewise normally run multiple asyncio/tornado/twisted processes in production as well. I don't see it as a big deal, or misleading to compare them in this sense.
