ProtoTRDNot really an issue, but more of a feature. In order to provide the Ethernet port without additional costs, they tapped into the USB bus. Otherwise you you need extra components, which cost. Also technically, the max speed of the Ethernet port is 480 not 100 thanks to the USB. So as long as you have no USB devices, and an gigabit input from the LAN, you should have quite good speed. Of course this is theoretically, and unless you have a NAS on your LAN, or really fast internet connection, it really won't make a difference. On the down side if you have a USB device plugged in, it will affect your speed, but only when read- write is performed and assuming you device is fast enough to actually cause a bottleneck.
