Hmmm... We have a couple running cef+pxf enabled and haven't
seen any CEF bugs, and we've lived thru a lot of CEF bugs in
the past. Not to say there aren't bugs, but I say it's not a
dead-in-the-water kind of thing...
As far as switching performance, the boost is suposed to come
with the "high touch" stuff where you're looking at more than
the IP address for routing decisions, otherwise you might as
well just get a NPE-300/400.
