 > 1. We could trim the list of perl cpan [https://github.com/macports
 /macports-ports/blob/master/_resources/port1.0/fetch/mirror_sites.tcl
 mirrors] to a more reasonable number.
 > 2. MacPorts base could spawn only a `ping` process for each host and
 perform the equivalent of the `grep` and `cut` commands using Tcl string
 processing.

 Why not both? :-)

 > 3. MacPorts base could limit the number of hosts that it checks
 simultaneously.

 That's not easy to do correctly and efficiently. The pings are run in
 parallel so that the overall time for the check is not the sum of the
 individual response times (which may be up to 3 seconds in case of a
 timeout).
