The invention relates to a method for measuring the performance of a network (18). The method includes steps comprising: parameterizing requests pointing to resources that can be accessed from a computer connected to the network, the parameterized requests being stored in a database; creating a user session comprising grouping together various stored requests; running a test campaign comprising concatenating in time the emission of the various requests in a session, each request being emitted by a user terminal connected to the network; for each one of the emitted requests, waiting for a response and calculating the value of at least one typical variable of the received response; and, aggregating the various values of the typical variable calculated during the test campaign to determine the value of a network performance estimator.
