Yeah, on the Pi the ethernet is still hanging off the USB2 bus. That wouldn’t be too bad if the various ports had their own buses, but unfortunately everything is hanging off a single usb interface coming out of the core cpu, so although the raw bandwidth is there to make 1G ethernet potentially worthwhile - you can plug in a 1G USB device if you want to - but as soon as you actually want to do anything you get contention on the bus and your throughput drops like the proverbial rock.
