Luit van Drongelen: Lightweight Python deployment servers

Filed Under:

Summary of talk at the PyGrunn conference.

Luit van Drongelen talks about Lightweight Python deployment servers, at the PyGrunn conference in Groningen, The Netherlands. Organized by Paylogic and Goldmund Wyldebeast & Wunderliebe.

I code python for fun (and hopefully eventually for profit). What is wrong with Apache? Well, nginx is much faster. You can double the responses and have much less memory usage. Apache has higher I/O load, e.g. for loading .htaccess file. nginx can natively connect to uWSGI: fast, light weight version of modwsgi. The protocol is uwsgi (so all lowercase). This is run separately from the web server. Tested on many operating system; not Windows, sadly.

So why use uWSGI instead of e.g. modwsgi. It's fast with a lower memory foot print. Can handle multiple interpreteer versions in multiple virtualenvs. Supports old and new WSGI standard. It can kill misbehaving worker threads; helps if you are coding those wrongly yourself. It can also handle long-running tasks. Configuration can be in ini files, json, environment variables, command line options, etcetera. Built-in message-passing system. Embedded (evented/async) HTTP server. It even has a clustering feature (beta at the moment). [Live demo of that feature, which worked yesterday.]

Some other WSGI servers show great performance too. For me uWSGI performs great and has good features.

Comment from room: look at this WSGI performance comparison.
