I'm not interested in how poorly you configure your
lab.

And, this thread was initiated because of unreasonable
behavior apparently caused by stupid attempts for
automatic flow detection followed by policing.

That is the real world.

Moreover, it has been well known both in theory and
practice that flow driven architecture relying on
automatic detection of flows does not scale and is
no good, though MPLS relies on the broken flow
driven architecture.

That is my point already stated by me. You don't have to repeat
it again.

Here, you implicitly assume large number of slower speed flows
against your statement of "higher speed flows".
