High-end routers and switches use dedicated h/w (ASICs or FPGAs) to move data, rather than shuffling all of it through a processor. Other, similar limitations exist, but through an FPGA you can likely push (roughly) an order of magnitude more data than through a processor due to a wider internal interconnect.
