Sounds like a bandwith-latency-product issue. TCP is prone to stalling at the end of a buffer window (in addition to reassembly and RPC waits). Multiple TCP streams scale linear with the available bandwidth over them. Single RPC messages should not split over multiple streams (causes reorder of segments), but different messages can go in round robin fashion. There is no need to ensure a symmetric path, so that the response comes back on the same stream.
