Is Tornado using multiprocessing internally?

Is Tornado using the multiprocessing module internally? Considering that Tornado, being a web server, needs to handle lots of concurrent requests, I think it makes sense for Tornado to use multiprocessing and therefore take full advantage of multiple cores.

If not, why not?

It doesn't not use multiprocessing. Instead, it uses non-blocking IO (only one thread and one process). See this blog post for a description of how it works and why it is fast.

Other servers like Gunicorn use separate processes to take advantage of multiple cores.
