There is of course a possibility, that the test doesn't simulate reality in the best way. The specs say 2gbit, but when doing 400mbps there isn't much power left on machines main cpu (10% idle). So i guess the limiting factor here is main cpu not the CA card. I have done the same tests with 1,8 GHz opteron and in that case the result was around 270mbps. Joosep
