What about a user-initiated step (port test-mirrors?), cached into  
one of the .conf files, that would simply compare ping results among  
the available mirrors. It could simply store the fastest mirror as  
the one to use. A user might be able to re-run the test periodically  
to determine the current fastest mirrors.

Perhaps we could follow some of the work done to find the fastest  
FreeBSD cvsup servers...


We already retain a list of mirrors for a given id (sourceforge, gnu,  
etc.), so we know the servers to query. MacPorts could store a  
"preferred mirror" for each id based on the fastest ping results.
