I had this to. I used to have 3 Realtek NIC's on my 433 MHz machine and 
without device polling I managed to have transfer around 35 Mbit/s and with 
device poling I had around 50 Mbit/s. Then I change my NIC's for Intel pro 
100/S ones and now without polling I get transfer around 58 Mbit/s and with 
polling enabled I get around 89 Mbit/s.
