With an average page response time of more than 17 seconds running across the group (as seen by 56kbps modem users), it is clear that retailers are much more concerned about delivering fancy graphics and dynamic banner ads to Internet buyers than they are with delivering acceptable performance levels to potential buyers. The huge bulk of dialup modem users will continue to abandon nearly one out of every two buying attempts on retail Web sites.
