Probably: build up the packet with cStringIO or with the array module instead of as a list of small strings. But if you time both versions I don't think it'll matter much. Python (at least CPython) simply will not be very fast no matter what you do. The overhead of building a large string (with ''.join, say) from a bunch of small ones isn't that big a deal compared with what you already lose in interpreter overhead running the application. -- http://mail.python.org/mailman/listinfo/python-list
