Reading the outbound data performance bit intrigued me. I believe the usb gadget interface on the BBB should theoretically be capable of much higher speeds than the onboard 10/100 NIC. You may simply be missing some performance tuning. Have you ensured that you were using the latest useable kernel and usb-cdc-dma? I can't test because I have neither a BBB nor a prudaq.

I've observed RNDIS speeds on the BeagleBone Black consistent with the ones documented on the wiki ~80Mbps, but then they turn out to be slower than the Ethernet. Had this feeling as well that speeds could be more as the USB is capable of pulling 480Mbps theoretically but never got to understand the bottleneck.
Anyone looked at the SanCloud Beaglebone Enhanced? It claims a GigE port but documentation is hard to find and I can't be certain how it connects to the CPU.

As far as I understand, the GigE is part of the CPU and just requires the proper MAC. I have tested the
SanCloud BeagleBone Enhanced and got
iperf -c beagle_bone_ip -t 30

Looks to me, that clearly outperforms all other interfaces by a huge margin.
