Due to the nature of TCP, delay-product has throughput effects even if everything has been optimized, stack- and application-wise.

That being said, have you been able to check the layer-2 stats on each of the ports in the chain, and verified that speed/duplex settings are either auto-negotiating properly or are hand-configured in matching configurations on each side of each link?
