First of all (perhaps I should have stated this in my first post), no,
I have not tested 28xx at 200 Mbit/s.  I have run those (2821 and 2851)
at traffic levels of about 40-50 Mbit/s max.

According to the router performance PDF, the 2821 does 87 Mbit/s, no 
access lists, no routing protocols, no nothing, 64 byte packets.  I
usually don't assume much more throughput than this document states,
as, even though they measure using 64 byte packets, they assume 100%
load (no room for anything out of the ordinary) and as plain setup as
possible, no dynamic routing, access lists, QoS...etc.

Your requirements may vary...
