Abstract In this paper, the service performance model for Web system based on HTTP
is presented, in which the Web server and the communication network are considered as one system to construct an open Markov queue network. This model is also extended to multiple-
server system. After analysing the effects of the parameters on the performance, the method to avoid deadlock and the speed rule to add new server are investigated. Finally, several schemes for improving Web server performance based on different congestion conditions are evaluated and compared. Simulation results confirmed the validity of the model.
