What you'll need to correct that is a way to increase the TCP window size of the hosts, thus reducing the time spent waiting for ACKs to be returned. -C
Catch is, the bw x delay product will kill you on these links if you run TCP sessions and you won't get anywhere near line rate. There's a company in Boulder which used to make a widget for high speed data transfer across sat link exactly for this purpose. Can't remember the name, should be able to find them easily though if they're still in business as it has been a few years since I last touched this stuff...
