This tutorial is a practical exploration of using Python coroutines (extended generators) for solving problems in data processing, event handling, and concurrent programming. The material starts off with generators and builds to writing a complete multitasking environment that can run thousands of concurrent tasks without using threads or using code based on event-driven callbacks (i.e., the "reactor" model)

Tornado comes with limited support for WSGI. However, since WSGI does not support non-blocking requests, you cannot use any of the asynchronous/non-blocking features of Tornado in your application if you choose to use WSGI instead of Tornado's HTTP server. Some of the features that are not available in WSGI applications: @tornado.web.asynchronous, the httpclient module, and the auth module.

in other words: WSGI sucks

Smisk is a simple, high-performance and scalable web service framework written in C, but controlled by Python. Smisk is currently used in production by Spotify and Livebloggen.

EvServer is a lightweight http server, created especially to host python WSGI applications. Additionally, it supports little known Asynchronous WSGI extension, which was suggested by Christopher Stawarz. Using this extension it's possible to create an output html response in many data chunks, without blocking the main server process while your application waits for external resources.

Comet the WSGI way.

Pipe viewer is a terminal-based tool for monitoring the progress of data through a pipeline. It can be inserted into any normal pipeline between two processes to give a visual indication of how quickly data is passing through, how long it has taken, how near to completion it is, and an estimate of how long it will be until completion.
