As a side note I was now for the first time able the transmit a 1GB File in a reasonable time and ran into the twisted bug that rekeying is broken. Since this window size seems to be a different one then the TCP window size it seems to be harmless. So I think the default winow size of paramiko should be raised to be at least 134217727īut maybe even higher. Here are some (non scientific) performance measurements with client and server on the same localhost ans = paramiko.Transport((hostname, port))Īnd then I reduced the window size back until I saw the first performance degradations.
