Well, I get about 0.9MB/s using scp to copy from the original file to
localhost. The overhead on both ends of the transfer undoubtedly explains
the (slightly) lower transfer rates.
OTOH, I recall that people are using this level of hardware as routers, and
I recall them getting about 30Mb/s (or 4MB/s) through them. Is there really
that much overhead with scp?
