Abstract

A method, computer program product and apparatus are disclosed for generating response time data for a client accessing information from a network. In one of the embodiments first instructions are attached to a first block of information. The block of information is available for requesting by the client from the network. The first instructions are for causing the client to read a first reference time, responsive to the client initiating access to a second block of information from the network. Second instructions are attached to the second block of information. The second instructions are for causing the client to read a second reference time responsive to the client loading the second block of information, and for causing the client to retrieve the first reference time and compute a time difference between the first and second reference times.
