Oh! I'm not sure why but I never paid attention to the speed of your cores. I suspect that has a huge impact. From what we were looking at it seems like you are capable of handling at least 500Mbps/core.
I'm not sure what the cost differential is between the mid-range processors and what you have in that box, but I'm starting to wonder if the world has been flipped upside down and suddenly the high-end processors are worth the extra expense now (for Bro at least).
As Vlad pointed out, I suspect that the DAG card doesn't really give any performance benefit over the Myricom nics. Although, both of those give huge benefits over something that isn't skipping the network stack and getting rid of interrupts.
