What target are you using? "nullio" mode or memdisk is good for benchmarking, 
if either of those are possible on your target.

How did you measure the latency? Are you using direct crossover cables, or

How does your NICs perform with for example FTP? How about iperf? 

How did you get those 50/100 and 500/600 Mbit numbers? What benchmark did
you use? What kind of blocksize?
