Recently I've started seen a strange behavior of dnf while downloading
RPMs updates: some packages are downloaded at the usual speed of my
connection (ca. 10MBps), while other packages, in the same transaction,
shows really slow download speed (<100KBps).

Does dnf uses different mirrors to download package updates in the same
transaction? Is there a way to show the mirror dnf downloads the updates
from? Running dnf in verbose mode doesn't show any clue.

Yes AFAIK. I've occasionally had slow downloads for a long time (years) and chalked it up to a slow mirror, but now that you mention it it does "feel" like it's happening more frequently lately.

Also (and my memory may be faulty here), I believe with yum you could "ctl-c" once during a slow download and it would find attempt a new download (presumably from another mirror) but this doesn't work with dnf. 

Thanks,
