When using HTTP/1.1, it's actually often faster to use a single connection
instead of multiple connections - especially if you are downloading several
pages from the same site. You can look at this paper for some more details:

Yes, you are right - there are some connection management problems in the
FTP module - it is primarily a question of bit rot - it hasn't been updated
as much as the HTTP module. It may be connected to a problem of listening
on a port doing passive data connections.
