The 4% increase in available bandwidth is only part of the equation though.
I would think that having to encap/decap 1/6 the number of packets(frames)
from host to host and all routers/switches along the way would be
beneficial, especially since some of these could be processing these in
software.  Certainly if there are FW or IPS involved.  I'm not sure about
the host side of things, but I'm guessing there would be efficiency
increases there as well.
