Hello,
There is a docutils specific mailing list:
docutils users <docutils-us...@lists.sourceforge.net>
You will need to subscribe from sourceforge, or you can just post your
patch on sourceforge:
http://docutils.sf.net
Another patch was recently submitted by Georg Brandl offering a similar
speedup. No idea if it is in the same area or not.
All the best,
Michael Foord

Hi, all.
I'm a member of Japanese translate of Python document Project.
We complete translating Python 2.5 document last year and now
work for Python 2.6 Document.
I feel building document is slow a little. So I try to tune docutils
and Sphinx.
Attached patches make building document 30% faster.
(In my environ. 330sec -> 220sec roughly)
I post sphinx.patch to bitbucket, but I don't know where to post docutils.patch.
Could anyone review these patch?
These patches changes following:
1. Use PyStemmer instead of PorterStemmer.
PorterStemmer is implemented Python and consumes about 50seconds
during buid.
PyStemmer <http://pypi.python.org/pypi/PyStemmer/1.0.1> implemented in C
and consumes only 7 seconds.
But searchindex.js with PyStemmer is different to one with PorterStemmer.
2. Avoid building OptionParser many times.
Sphinx uses docutils.core.publish_parts() without `settings` argument
many times.
This causes building docutils.frontend.OptionParser many times and consumes
29 seconds.
3. Avoid building NestedStateMachine many times.
NestedStateMachine is built and destroyed many times.
Recycling that SM make significant performance gain.
