Not the first time we've seen these kinds of benchmarks. Microbenchmarks
rarely give you interesting information about real world apps. Also: ab
ain't a very good HTTP benchmark.

But hey, data points are data points.

[Twisted-Python] txriak module released.

2010-04-24 Thread Ray Cote 
Hello Twisted:

An initial release of txriak has been posted to PyPI:
  

txriak is a Twisted module for communicating with Basho Technology's Riak data 
store via the HTTP interface. 
Written in Python, it requires Python 2.5 since it uses the yield version of 
deferreds.
Initial release was written to match as closely as possible the 0.9 riak.py 
Python module released by Basho Technologies. 

Hope others find this to be useful. 
Look forward to comments and feedback.

I didn't notice the benchmarks...good catch. I was more interested in
the conciseness or lack thereof with the various frameworks. Very
surprised that Twisted was nearly as clean and easy to read as the
Eventlet example.

This comparison (in the blog post) makes the same mistake that many such 
comparisons make.  The division of libraries into the arbitrary 
categories of "reactor model" and "coroutine" is artificial.

See corotwine for an example of using Twisted and coroutines.  And see 
txwsgi (announced here a week or two ago by Manlio Perillo) for a 
Twisted-based wsgi container which supports applications that look 
almost identical to the eventlet/gevent wsgi applications used in this 
comparison.

And take a look at how eventlet and gevent are implemented, and you'll 
find something that's essentially the same as a Twisted reactor.
