There are no real outlyers in the datasets for both the py2exe and python runs, just a 6-fold average increase in the time deltas for the py2exe run. This leads me to believe that there's no single point of slowdown under py2exe that needs investigation, just a sort of overall slowdown.

Try to turn off antivirus software on your machine.

Would it be possible for you to generate the smalles possible source  
code example that shows this behaviour on your computer so we can try  
reproduce it?

Still working on this. A question: does py2exe add any overhead to C
shared library calls?

Try to turn off any antivirus software on your computer, and check again.
