That's absurd.  There's no way that an NPE-400 box is going to add any
significant amount of latency with such a small a connection off of a PA-A3
(or even A6 or whatever), unless the box is being constantly hammered through
other higher speed ports.

I've used NPEs and VIPs with PA-A3 cards for at least 4 years now and the 
results have always been excellent.  Even the CX bus AIP adapter running
with an old RSP2 (test box :) handles 20Mb loads gracefully.
