All of those numbers are straight forwarding with nothing turned on
and 64
byte packets. That way you get a nice idea of what the CPU can do.
They're also, as ever, unidirectional, so you can immediately halve them if your question is "what size pipe can I connect this device to?"
As a VPN managed CE, with QoS, BGP, a little bit of IPSLA etc, I'm seeing a practical limit of around 70Mb/s bidirectional out of the 3845.
