Description
Per #327 (performance measurement of directories), let's run a good Python profiler on directories. Allmydata has a licence for the proprietary Python Performance Validator http://www.softwareverify.com/python/profiler/index.html (works only on Windows), and it is a good tool so I'll use that.

exarkun recommends the cProfile profiler (built into the standard library).

Oh, and using oprofile is easy and often shows you something interesting.
