I've never used Pyro, but for a fast network file transfer in Python, I'd probably use the socket module directly, with a cache oblivious algorithm: http://en.wikipedia.org/wiki/Cache-oblivious_algorithm It doesn't use sockets, it uses files, but I recently did a Python progress meter application that uses a cache oblivious algorithm that can get over 5 gigabits/second throughput (that's without the network in the picture, though if it were used on 10 Gig-E with a suitable transport it could probably do nearly that), on a nearly-modern PC running Ubuntu with 2 cores It's at: http://stromberg.dnsalias.org/~strombrg/gprog/ . For a simple example of using sockets in python (without a cache oblivious algorithm, unfortunately), you could glance at this: http://stromberg.dnsalias.org/~strombrg/pnetcat.html HTH :) -- http://mail.python.org/mailman/listinfo/python-list
