This isn't as silly as you think.

At the February NANOG, Van Jacobsen showed the results of some research in
which they discovered some situations where web pages could be retrieved
over a 28.8k modem link faster than over a workstation connected to
Ethernet, connected to a T1 line.

Just remember, that TCP flows are not water flows and aggregated TCP flows
in a big pipe do not behave at all like aggregated water flows in a big
pipe.
