As I understand it the yum-fastestmirror plugin will take the list of
mirrors, test them, an make a list of mirrors top speed down, and make
note of *your* fastest mirror. Yum then starts there and only switches if

The 'available packages' list is only kept for a certain, set(but
changeable), length of time. Why? Well they do change don't they? ;-)
