Registering 20,000 devices *is* a real world problem (I'm actually aiming
for 100,000, as that's what roughly fits in a single 10Gbps link -- something
that a mid range system can now route). When an edge router comes up from
reboot, or after a link has been down, the rate at which customers connect
is important -- too slow, and you get a pile of support calls from customers
complaining that their connection is down. Because of the data structures
used, there isn't even any improvement from an SMP system, so this needs
to be addressed directly.
