Of course, it's hard to prove a negative, especially about large

BGP performance curve.
Strictly speaking John is, of course, correct. We should continue to
see linear degradation in performance as the table grows.
However, some speculate that we will see a knee in the number of
prefixes that are carried in the DFZ. In these scenarios, as a
market for v4 prefixes is established, it will become easier for
organizations to acquire PI prefixes and inject them. Further,
existing space holders will tend to de-aggregate them so as to
maximize their market positions. This combination could possibly
lead to a knee in the size of the overall table and a resulting knee
in overall Internet convergence time.
I should stress that this is all speculative at this point and we
will simply have to see how it all plays out.
We live in interesting times.
