Dnf is blazing fast for resolving the transaction. Alas, this big speed difference wrt yum is often totally eaten up by yum using fastest mirrors. In my case I have a 100 MB connection at home, so yum usually downloads at ~8MB/s, while for dnf the speed can be just ~300kB/s.
dnf should get the same kind of mirror logic as in yum-fastestmirror.
This is highly relevant, yet has to wait for the rest of the API/plugin API to be ready first. Give this some time please.
Current development version of Librepo (a library which is used by Dnf for downloading metadata and packages) has a LRO_FASTESTMIRROR which does same thing as the yum-fastestmirror:
