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?
