At the system call level, recv() is marginally faster since there's less data to pass back and forth between the kernel and user space. Not that this is likely to be significant in any real-world application. The bigger advantage to recv() is that the interface is simpler, so there's less code to write. For the C interface, using recv() instead of recvfrom() frees you from having to pass in two arguments that you're not going to use. From the Python interface, it frees you from having to unpack the tuple that recvfrom() returns. Instead of: data, address = recvfrom(bufsize) you write data = recv(bufsize) It's not just a bunch less typing, it's also easier to understand. You don't leave some future maintainer of your code scratching their head trying to figure out where 'address' is used, when in fact, it's not. -- http://mail.python.org/mailman/listinfo/python-list
