Huh. I learned two new Python facts this week: 1. print statements were slowing down my code enough to really notice a particular transition. It went from about 2-3 seconds to a bit under 1 second. What at first seemed unresponsive now seems almost snappy. The only difference was removing a lot of print statements I had used for debugging (Python 2.5, on a single core 1.97 Ghz machine).
2. Merely having a cPython decorator for profiling a function significantly slowed down performance...again, from a about 2 seconds to just under a second (~1 second doesn't seem much but these sorts of delays do affect user experience). There is something ironic or Heisenbergian about that. -- https://mail.python.org/mailman/listinfo/python-list
