A computer implemented method adjusts a Web page including multimedia content according to the effective bandwidth and/or latency monitored on a network path connecting a server computer storing the Web page, and a client computer requesting the Web page. In response to receiving a request for the Web page in the server computer from the client computer, the server computer, or some other computer closely connected to the server computer monitors the effective bandwidth and/or latency of the network path. Using the measured effective bandwidth and/or latency, the content of the Web page is dynamically adjusted by the server computer while sending the Web page to the client.
