Kudos to the >FreeBSD team for developing a stack that uses no resources. .... For the record, what I was saying was that a decent machine (e.g. 2.4 PIV) should be able to push 200,000 packets per second with decent NICs (em, or fxp) and with a median packet size (see www.caida.org) of about 540 bytes, that works out to ~ 100Mb/s. >Since its clear you have no idea what you're talking about, perhaps if >someone who actually does would like to pipe in it would be useful.
