I would not have expect the problem to be so severe with that link speed.

Try using the gtk or wx backends; they are much faster in this use case. With or without those backends, you can also try using the -C option to ssh to compress the data, although normally it would be only for slower connections. But if you are not getting fast response with the gtk or wx backends, then I suspect there is a networking problem, probably involving a latency or lost packets.
