PackageKit is something different. How often does it connect with remote
repositories to look for new metadata? How long does it take to download
the metadata archives for multiple repositories (= multiple MB each).

The first time you would run "yum update" on a machine that has been
offline for a long time, it would notice that the timestamp file
/var/cache/yum/i386/12/updates/cachecookie  is a lot older than 1.5 hours,
and hence it would connect to the "updates" repo to check whether more
recent metadata are available.
