Just thought I'd throw out the tool I am using for my "experiments". Python Performance Validator - an (expensive) commercial product to be found at http://www.softwareverify.com/ Working with a free fully functional 30 day trial version, seeing what I can learn about my code with it before it expires, and then will probably be left to other tools, as I can't justify its cost for my purposes. But at least I can give them a plug. I have found profiling, formal debugging, etc. somewhat complicated by the fact that I am working with a graphical and dynamic application. Not that that's so unusual a situation to face, but some of the issues that arise seem to me to come under the category of Profiling 103, and I never got through 101. This tool has helped me get my bearings.
