can you elaborate?  under what circumstances can i get better
throughput?  if i could squeeze a little more life out of the
7206VXR/NPE300 combination as an LNS, that would be spiffy.

i already pre-clone more than enough interfaces considering how many
customers i have pile on to the box.

a cursory search found this:

i'm running 12.3T; did i get this by default and not realize it?

thanks,
