With old Realtek and MTU 1500, throughput was about 10 Mbytes/s.
With a new Intel adapter and jumbo frames, I obtain the same result

I suppose there is somewhere a bottleneck, but where ?

1. Are ethernet cards on either end gigabit adapters?
2. Are the cards configured as such by their respective OSes?
   (use ifconfig -v ifname)
3. Is the ethernet cable between the two machines Cat-5E or
   better (with all 8 wires)? (Performance is sometimes not up
   to spec with some cards and mere Cat-5 cables.)
