This does not make your transfer faster because as you probably know
the SFTP channels are combined in one session, which means in one TCP
connection.
I think you only have two choices:
1. Help us improve performance of the libssh2 transport layer.
2. Use multiple separate TCP connections to the server. Note that
this is rather ugly behavior for a client, and note that you must
authenticate each connection.
