It may be the packet latencies that are killing your throughput.  Try
tuning your tcp stack to allow more packets to be sent before you have
to receive and ACK - in Solaris the variables are tcp_xmit_hiwat and
tcp_recv_hiwat, you need to find the Linux equivalents (I am not a
Linux person....).  This is a fairly standard tweak for high
bandwidth, high latency links.
