Just thought I'd throw out the tool I am using for my "experiments".
Python Performance Validator - an (expensive) commercial product to be
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
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.
What it solves for me is the problem of separating performance issues,
