Try a machine with a 64/66 PCI bus, or preferably, a PCI-X bus that can run 64/100 or better. I got line speed packet generation and reception on a dual 2.8Ghz Xeon machine with PCI-X (64/100) bus and a dual port Intel pro/1000 NIC. I tested with 1500 byte packets and transmitted and received 999Mbps of traffic between two ports (total of ~4Gbps across the PCI backplane). I wasn't routing or anything like that, but at least for packet generation it worked fine. Ben -- Ben Greear Candela Technologies Inc http://www.candelatech.com
