Abstract

Web prefetching mechanisms have been proposed to benefit web users by reducing the perceived download latency. Nevertheless, to the knowledge of the authors, there are no attempts in the open literature comparing different prefetch techniques that consider the latency perceived by the user as the key metric. The lack of performance comparison studies from the user's perspective has been mainly due to the difficulty to accurately reproduce the large amount of factors that take part in the prefetching process, from the environment conditions to the workload. This paper is aimed at reducing this gap by using a cost-benefit analysis methodology to fairly compare prefetching algorithms from the user's point of view. This methodology has been used to configure and compare e of the most used algorithms in the literature under current workloads. In this paper, we analyze the perceived latency versus the traffic increase to evaluate the benefits from the user's perspective. In addition, we also analyze the performance results from the prediction point of view to provide insights of the observed behavior. Results show that across the studied environment conditions higher algorithm complexity do not achieve better performance and object-based algorithms outperform those based on pages
