When I speak of the C2758, I speak of the product sold at the pfSense store, as sold by the pfSense store, not the generic pfsense release running on "some brand of board@. > (I think it’s more a problem with the nics than the cpu) You seem confused. > I recently tested various nics and cpus to see if the systems I was building > could reach Gigabit Ethernet's max throughput of 1.488Mpps on one port Please show your work.
