I've been quite surprised with the performance of the 2821. We currently
have one in a trial as a small-POP (500~ DSL users) BRAS terminating PPPoE
users. We're getting 700 users doing up to 50Mbit of traffic at about 60%
CPU. Our per-user configuration isn't optimised for virtual-template
subinterfaces yet either - so we could squeeze a bit more CPU out of the
box yet.

So yes, even with some features (ACL, QOS, etc), the 2821 should handle E3
just happily.

Rgds,
