Apart from being connectionless, `HTTP` also is a stateless protocol i.e. server doesn't maintain the information about the client and so each of the requests has to have the information necessary for the server to fulfill the request on its own without any association with any old requests. And so this adds fuel to the fire i.e. apart from the large number of connections that the client has to open, it also has to send some redundant data on the wire causing increased bandwidth usage.

Here’s a problem: we want to download a file with BitTorrent, but it’s a peer-to-peer protocol and we have no idea where to find peers to download it from. This is a lot like moving to a new city and trying to make friends—maybe we’ll hit up a local pub or a meetup group! Centralized locations like these are the big idea behind trackers, which are central servers that introduce peers to each other. They’re just web servers running over HTTP, and you can find Debian’s at http://bttracker.debian.org:6969/
