I seen similar results at a customer site with testing - I asked the person who was looking into this ... response I got was "that's about right for a switch running at line rate"... never took any time to understand his response. Does this make sense to anyone else? My understanding of "line rate" was simply that a 10GE port could do 10GE (or VERY close to it). Thankfully that particular site does about 3.5Gb/s so no major issue...
