Because of the FCC regulation, 56k connections are limited to a
theoretical maximum of 53kbps. That's around 6.625kBps downstream (to the
client). This does not include issues related to line noise, possible
congestion in the connection(s) of the ISP to the Internet, and whatever
overhead TCP/IP and PPP may impose vis a vis connecting directly to some
node using, for example, minicom using zmodem or some other similar
transfer protocol.

A nice way to test to figure out where the bottleneck occurs is to use
IPTraf (or some other tool, of course, it's just that I really like
IPTraf) to monitor the link while downloading (1) a file that resides on
your ISP's server, and (2) a file that resides somewhere else. The first
test will allow you to max out your dial-up connection, isolating it from
the congestion between your ISP and the rest of the Internet. The second
test should show you exactly how fast things are going.
