Yes, this was bizarre - it is the opposite of what you saw on opterons.

I just wanted to make sure that i can see some consistency with the simple case. Anything i should tune with routing?

Thanks for fixing this. > oh - they are fixed finally ;-> I didnt pay attention. BTW, with flow control another bizarre thing: 50% or so of the times i tried with flow control on, I did get better numbers with flow control than when i turned it off totally;-> But because it is so undertemisnic it is hard to reproduce consistently. It needs some further thought/analysis; it is possible the switch is messing something. cheers, jamal - To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
