Dave - I'm certain that I have non-x86 devices that can forward more than a gbit/sec in both directions. If only because I have a very nice system based on LS2160A ARM implementation that I use to forward 10 GigE traffic in both directions. Though the packets are not tiny. It's not cheap, of course. I am running Fedora server on it in my lab. The LS2160A carrier comes from a company called SolidRun. I do understand that many of the low end ARM boards (and maybe even the Pi4 Compute Module) have driver/bus weaknesses. Have you tried to understand what the issues are? Could be Linux kernel and driver issues specific to the GigE hardware. Though I'd assume that USB 3.1 would not inherently get in the way. I currently use a Celeron board with 2 1 GigE interfaces for my 1Gig cable connection, running Linux configured according to my preferences. As you say, x86 boards and PCIe ethernet interfaces tend to be fine with two 1 GigE ports. So maybe you want to be a bit more specific about what you mean "device on the market"?
