We have seen something like 10-15Kpps. There is a group at MIT working on a FreeBSD-based router, see http://ana-www.lcs.mit.edu/anaweb/pcrouter.html As I recall they talk about forwarding 500Kpps through the kernel, perhaps 50 - 100 Kpps through the interfaces. They use a modified FreeBSD and two CPUs, one to do the forwarding and one to handle the gated calculations. It's well worth looking at. -- Jim Dixon VBCnet GB Ltd http://www.vbc.net tel +44 117 929 1316 fax +44 117 927 2015
