I don't know the details of the new metadata format, but I believe I
heard Seth talking about there being a single signed file containing
hashes of the others. You only need to grab that small file often, the
others far less often.
Watching my web server logs, surprisingly a higher amount of total
bandwidth usage is mainly in .hdr files compared to the apt bz2
compressed metadata. Roughly 60% of the users using my mirror are apt,
40% yum.
