I'm considering putting some new servers running BSD in place purely for sniffing capability, and am quite content with TCPDUMP, but it won't be a very wise investment if I start losing packets at, say, 100Mbps. I've seen it said that BSD is much better for this type of thing than Linux, but numbers are heard to come by. Right the right NICs and processing power, is line-rate 1Gbps possible?
