Perhaps I am missing something? > I'm not sure what you mean with "overall" but if you have access to a computer running the discard or echo service at the other end of your upstream-link (jasonlim.com <----AGC/upstream----> computer B) then you can run tcpblast on one of your jasonlim.com-computers ($tcpblast <ip/hostname computer B> <number of KB you want transfered>) and that should give you the maximum bandwith your upstream provides (repeated a number of times to eliminate errors).
