You might want to doublecheck your setup then, as I'm not having this 
problem.  I have these in service on my backup network and they have no 
problem hitting 1gb full duplex on each group of 8 ports.  A quick eyeball 
of outbound traffic graphs on ports 1-8 of one of the cards gets me 300 + 0 
+ 0 + 300 + 200 + 150 = 950.  Seems about right.
