In the dnf case only a repomd.xml (one for each repo, <5K) is download every time metadata cache is expired, and only changed metadata will be downloaded (repodata/*.xml.gz), the Fedora repo dont change, so it is only downloaded once, Updates is composed once every day, so it will only be downloaded one a day. Rest of the content of cache/dnf is generated from the unpacked metadata, so the size of the directory don't tell any thing about how much metadata is downloaded and how often. Tim
