you tend to be more often then not CPU bound because of features, etc
on a 7200. if you are not cpu bound, you can push it past
the 300+ meg limit of the PA-GE. i don't remember the exact hw config
that produces this but i believe if you are moving packets from an
IO based GE interface to a GE PA you can cross the 300+ mbps boundary.
or it might be IO to IO. i will check around and let you know when i get
the chance.
