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. == before == ncalls tottime percall cumtime percall filename:lineno(function) 25720/459 0.997 0.000 134.085 0.292 tools/docutils/statemachine.py:178(run) 92281/1513 1.420 0.000 133.935 0.089 tools/docutils/statemachine.py:384(check_line) 25720 0.184 0.000 89.628 0.003 tools/docutils/statemachine.py:129(__init__) 25720 0.632 0.000 89.444 0.003 tools/docutils/statemachine.py:448(add_states) 385800 1.665 0.000 88.813 0.000 tools/docutils/statemachine.py:436(add_state) 385800 2.356 0.000 85.287 0.000 tools/docutils/statemachine.py:928(__init__) 385800 1.793 0.000 82.931 0.000 tools/docutils/statemachine.py:566(__init__) == after == ncalls tottime percall cumtime percall filename:lineno(function) 25720/459 1.051 0.000 68.175 0.149 tools/docutils/statemachine.py:178(run) 92281/1513 1.405 0.000 68.024 0.045 tools/docutils/statemachine.py:384(check_line) 6862 0.031 0.000 24.241 0.004 tools/docutils/statemachine.py:129(__init__) 6862 0.174 0.000 24.210 0.004 tools/docutils/statemachine.py:448(add_states) 102930 0.430 0.000 24.036 0.000 tools/docutils/statemachine.py:436(add_state) 102930 0.633 0.000 23.162 0.000 tools/docutils/statemachine.py:928(__init__) 102930 0.549 0.000 22.529 0.000 tools/docutils/statemachine.py:566(__init__)
