Is there some setting for a minimum bandwidth threshold or some other way to diagnose some really slow mirror?
Add the fastestmirror directive to /etc/dnf/dnf.conf
That won't give you a minimum bandwidth but it will find what it thinks is the fastest mirror to download from. (Not guaranteed to be the fastest since it measures ping response time at the start and picks from there, but it's more than nothing.)
