As far as I can remember that sounds pretty much like the information that I got from Cisco when I asked.
so i would think that is quite typical
but I think that was for switching. I would guess that it would add some time to route also.
however I do not know if there is a time difference in routing on the physical port itself or on the vlan in the switch.
if it is fast routing you need, then I would take a look at the specs for the nexus 7000.
I have no figures for itt but thats where i would start.
if however you are able to do switching, then i would look into the 4900 or the nexus 5000.
they are quite a bit faster.
Another tip to save some nano seconds.
cables in the right lengths. and right model.
check signalspeed in copper and different types of fiber, the results might surprise you.
if you are just trying to send information from one server in the same rack to another, check out infiniband.
there are some amazing speeds set there.
as a general hint and without knowing your setup or purpose its my view that the network normally is not the bottleneck,
sure I understand its a race towards zero, so every nano second counts,
