Finally, since all the processes share the same port it is more difficult to monitor them individually on Tornado’s HTTP server. Warning: WSGI is a synchronous interface, while Tornado’s concurrency model is based on single-threaded asynchronous execution. Many of Tornado’s distinguishing features are
