The performance decrease is an artifact of CPython's rather primitive storage management (reference counts in every object). This is pervasive and can't really be removed. But a new implementation (e.g. PyPy) can and should have a real garbage collector that doesn't suffer from such effects. -- http://mail.python.org/mailman/listinfo/python-list
