I don't know about other mirrors, but I minimize my downloads by
downloading the CD images, running my mkdvd script on them to build a
DVD image, and rsyncing that to get the "real" DVD image.  I then
extract the DVD image to the os directory, run yum-arch and createrepo,
and rsync that to fix up timestamps.

I also only download the SRPMS images for one architecture; I copy them
to the other arches and rsync them to get them right (it seems to save a
significant amount of download time).
