[c-nsp] performance difference between RSP8 and RSP16

[Rodney Dunn]

Decrease in what CPU?

Process level or interrupt. 

If most of the traffic is being switched under interrupt
you sholdn't be seeing a 20% CPU on the RSP.

And I wouldn't think you would be seeing 20% on the CPU
for control plane work constantly.

During a reconvergence event that would make sense.
