The slow performance is most likely due to the poor performance of Python 3's IO, which is caused by (among other things) bad buffering strategy. It's a Python 3 growing pain, and is being rewritten. Python 3.1 should be must faster but it's not been released yet.
3.1a1 is out and I believe it has the io improvements. -- http://mail.python.org/mailman/listinfo/python-list
