That's the spec sheet, and that's for straight forwarding.
If you want to do much of anything else at all with the router,
Cisco has another web page that says they only recommend 45Mbps on the
3845 and something like half that on the 3825.
It's especially an issue if you need to do traffic-shaping, which you
usually do for MetroE.

Note that this isn't my regular email account - It's still experimental so far.
And Google probably logs and indexes everything you send it.
