Ugh.  I can't answer this - we have no Sup2T yet - but I would be very
much interested in whether you can get this solved.  We're currently
planning our "next gen" hardware, and it will either be ASR9001 or Sup2T -
and we're leaning towards Sup2T because "that's 6500, we know the 
platform"... (famous last words).

Maybe one of the "collect" items you are using is causing this high
load...?  That's at least what I'd try next - turning off all of
the complicated ones which need a FIB lookup (routing source/dest as, 
next-hop, interface in/out), adding them back one by one and see which 
one is killing the box...
