I searched for a bandwidth measurement tool and found only one - DU Meter http://www.hageltech.com/dumeter which leaves a good bit to be desired. After using it for a while in combination with PingPlotter, I would note that it would be a major improvement to have the bandwidth usage info/graph integrated with PP so that response times could be more readily viewed relative to bandwidth usage.<br><br>Generally, with some exceptions, I am observing spikes in bandwidth usage accompanying spikes in poor response time. I'm not sure of the technical reasons why response time would slow under load - it's kind of like the water flowing more slowly as one opens the water tap.<br><br>
