I think it depends on your platform/driver. For instance, I reach up
to 600 ko/s (receiving UDP packets) with current Xilinx drivers (on
PPC 405  @ 350 MHz, without OS), but Xilinx will release new drivers
with DMA support, so performance will be increased (probably up to 4
Mo/s).

Regards,
Cedric.

PS : be carefull with IP fragmentation ; it can slow down the speed.
