This depends somewhat on the service and protocol. The requirement to fill a packet is calculated and governed by a number of forwarding criterion.
Even the cisco router itself has a nagle algorithm for despatch. Where the first characters of a stream are forwarded at the expense of packet size, and assuming the session has some block characteristic, goes onwards then to improve packet size. I'd expect them to be 64Bytes not bits.
Where you encrypt you implicitly compress, so that doesn't help when there is payload redundancy of information. If only TRANSIT routers could coalesce small packets to make bigger ones...
Can't comment on the 12Mbit/sec performance personally. I'd be happy with that in my applications.
