sudo pip install bjoern

A screamingly fast, ultra-lightweight asynchronous WSGI server for CPython, written in C using Marc Lehmann's high performance libev event loop and Ryan Dahl's http_parser.

bjoern aims to be small, lightweight and very fast.

• less than 800 SLOC (Source Lines Of Code)
• memory footprint smaller than a megabyte
• no threads, coroutines or other crap
• apparently the fastest WSGI server out there
• 100% WSGI compliant (except for the write callback design mistake)

bjoern.run(wsgi_application, host, port)

# alternatively, the mainloop can be run separately:
bjoern.listen(wsgi_application, host, port)
bjoern.run()

Sucks. Really, the code is an incredible mess. It likes to segfault.

I tried to patch Fapws so that it would support threading, but after about two hours of brain slime feeling, I decided to write my own WSGI server -- "Fapws done right".

bjoern is about 5 times faster. Plus gunicorn is too much bloated.

Awesome project, but way too much bloat.

Unfortunately now bloated with gunicorn and coroutine/greenlet crap, seemed to be a very nice server at first.

Probably too much bloat, too slow, does not scale, buggy, ...
