Huh?

FTP requires the use of two TCP connections (control and data), as
compared to only one for HTTP.   Further, it requires more round
trip times to start the transfer due to the activity on the control
connection.

Regardless, once the bytes start spewing, it's hard to imaging how a
constant number of bytes is transported more efficiently for the network
using port 20 as opposed to port 80.

I can belive that the FTP daemon might more or less crocked than the
HTTP daemon on a host, but that's about it.
