Description of problem:
dnf update is now downloading packages in parallel.
but dnf makecache is also pretty slow
(depending on a network), making it fetch
cache from unrelated repos in parallel would
speed this up.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. run as root:
# time dnf makecache
2. compare time reported for each repo and total real time
each repo is updated separately, one after another,
total time is the sum of times for each repo
Total time is worst time for a repo.
Can some downloads be parallelized within repo?
Might be worth considering, but might increase load on repo servers.
