I believe the problem is MacPorts will wait for a while (10
seconds?) before giving up on a mirror which just drops packets
instead of refusing the connection outright. It does not break MP,
but it is pretty annoying. David should have explained the
limitations on the mirror at the beginning, but at least we know
now so a workaround can be put into the mirror selection.
For me it takes about 5 seconds to fetch zlib, of which about 1
second is actually downloading the file. For glib2, which is larger
and has more mirrors, it takes 11 seconds, of which about 7 seconds
are downloading the file. So either way, about 4 seconds for MacPorts
to set up and ping all the servers (including my local mirrors which
are offline and not responding to pings for this test). If we can
make MacPorts quicker at setting up and pinging the servers that
would of course be great, but 4 seconds doesn't seem all that bad. Is
this also what you're seeing, or is it taking much longer for you?
What workaround are you thinking of for the mirror selection?
