Well, if this is a fresh install we're talking about, then you're probably just seeing the effects of the automatic updater. Since Fedora wants to protect you from doing double updates, you can have only one updater at a time. In other words, while the automatic updater is running, you cannot use yum or pirut. It is usually quite fast - except after a fresh install, when it has so many files to check and updates to retrieve that it could easily take half an hour or more before it pops up a box to inform you that there are over a hundred updates available (=800+ MB when I installed last month...).
Edit: if yum is doing OK, then clearly all of this isn't much of an explanation. Sorry for overlooking this part. Are you sure that the "enabled" item is set to 1 in your repo files?
