I've always thought it moved fairly fast.  This output is while I'm at
work, and the mirror that it uses never changes (1Gb connection to this
mirror), but it still has to pull the info from some sort of DB ("cached
hostfile") and possibly test the mirror to make sure it's still valid.
While I'm at home the mirror may change a little bit, but I think it's
mostly due to it being a DSL line and therefore slow.

I do think the fastestmirror plug-in adds value; if people are
experiencing delay directly caused by the plug-in, perhaps there are
some optimisations that can be done.
