Sorry guys, I'm not stupid (I think). I can open IDLE with Py 3.2 ou Py 3.3 and compare strings manipulations. Py 3.3 is always slower. Period.
Now, the reason. I think it is due the "flexible represention". Deeper reason. The "boss" do not wish to hear from a (pure) ucs-4/utf-32 "engine" (this has been discussed I do not know how many times). jmf -- http://mail.python.org/mailman/listinfo/python-list
