Yup. This squares with my observations. My cable modem is rated at
about 10Mbit/sec (supposedly the same rate in both directions), and I have
observed ftp transfer rates up to about 500Kbyte/sec or so (when sending to
another local machine). There seemed to be a difference between sending and
receiving data as I was only able to get about 250Kbyte/sec receiving. The
fact that I am seeing this slight dropoff indicates to me that I am pretty
close to the maximum throughput of one of the two machines.

The irony is that the connection to the outside world is a T1,
so I am throttled any time I want to got outside to play, but I won't
ever complain about getting T1 performance :-). Not for a while, anyways.
