Well, a lot of that time may have been downloading metadata.
for me on rawhide here's it runs with this timing:

again - do you know if there was any metadata download? How much time
are you seeing in total?

If you run yum like this:

echo 'n' | yum -d3 whatever command | grep 'time:' then you'll get the
timing outputs for each major operation yum does.
