I'd be checking MTUs everywhere, especially if he's on ADSL. Can he do other large transfers over the OpenVPN link to the same server?
He says (this is going to be awkward!) on our irc channel:
nickb I assumed that MTUs would affect throughput a lot but not the fact of it arriving. nickb Is this because of udp? nickb tcp will break up and reassemble packets
Yes, I'm well aware of that.
But.
You're layering OpenVPN on top of a UDP based network and there can be issues with the lower layer telling the OpenVPN wrapped layer that there is a need to fragment.
You didn't answer if you can do other large transfers to the same server. What about without OpenVPN involved (using eg ssh as the transport instead)?
