Prefetching Inlines to Improve Web Server Latency.
Ronald C. Dodge Jr., Daniel A. Menascé · 1998
this paper, we analyze, through simulation, the potential benefits of having the server also parse the document and pre-fetch into its main memory cache the inlines that will be requested by the remote client. The parameters for the simulation were obtained from a detailed workload characterization of a Web server available to the authors. Response time improvements of up to 48% can be achieved with even moderate cache sizes. 1. Introduction The Web has experienced an exponential growth since its inception. Recent statistics from a 1997 Nielsen Media Research study put the number of Web users in the US at 45 million and in Canada at 5 million. Applications such as electronic commerce and digital libraries will help to further increase the growth rate. Electronic commerce is forecast to be a $6.9 billion industry by the year 2,000. Currently, 85% of America's Fortune 100 companies have a presence on the Web and spend between $0.75 and $1.25 million on their Web si
