The RPi's 10/100 ethernet controller is connected to the BCM2835 SoC via it's USB controller, so the USB controller has to share it's bandwidth between the peripherals. The BBB also has a 10/100 ethernet, but it's directly supported by the SoC, so the performance *should* be a little better, particularly when there's other USB traffic.
