Has anyone done any performance tests on this ? I'm interested in knowing what can of bandwidth/pps one actually can achieve on a PC router. If the NIC now is the limitation(?), how much OS resources do I have left after the NIC is running at 100% ? I'm looking at building a new network, using pc routers for some of the bgp stuff can save quit a lot of money. /Tony S
