Thanks for this.. turned off netflow export.. and it dropped our qfp load
from 44% to 18%. ugh..

That's what I thought.
Our total inbound bandwidth from upstreams is about 20G at max.. so that
really is the total bandwidth...
Now we are terminating about 1800 PPPoE sessions on the router as well, and
have policing set on them, as well as shaping on a couple of our major
downstream links.

In the past we had packet loss issues due SIP's PLIM buffer.
The following docs may provide some guidance:

I mean a router without ASIC based forwarding like a Juniper MX or Nokia 7750.
The advantage of the 1k is you don't need a services card for cgnat, but the
large disadvantage is everything passes through the ESP processor and this
often leads to disappointing results under load.

Hi
we see similar problems on ASR1006-X with ESP100 and MIP100. At about
~45 Gbit/s of traffic (on ~30k PPPoE Sessions and ~700k CGN sessions)
the QFP utilization skyrockets from ~45 % straight to ~95 % :(
I don't know if it's the CGN sessions or the traffic/packets causing the
load increase,
