Hopefully it works this time. > Hi, I haven't tried comparing this sort of performance with Linux so your conclusion still might be right, but the fact that you couldn't saturate 1 Gbps on either system even with big packets suggests that there might be an external problem - a bad network card or a bad driver for the network card, or a switch whose line discipline is a bit in conflict with the NIC or the driver. I have previously successfully (and rather trivially) saturated 1 Gbps links with Broadcom cards with FreeBSD 7.x, so it *is* possible.
