Saperlipopette!: a Distributed Web Caching Systems Evaluation Tool

Abstract:

Designing a distributed cache infrastructure to improve the Web performance for the users of a large-scale organization is a difficult task. To guide the decisions of system administrators, we propose Saperlipopette!, a tool that can be used to evaluate, a-priori, the quality of the service offered by each potential configuration of the distributed cache infrastructure. Saperlipopette! is based on trace-driven simulations. Our methodology is two-fold. First, we monitor the targeted organizations' Web related activity. Second, we replay the organization's access pattern while simulating the distributed Web support infrastructure.

This paper presents the information gathering as well as the design of the tool. We show that beyond a certain cache's size, the performance stays constant whereas the consistency continues to decrease. We also evaluated a number of distributed configurations, among which peer-to-peer Relais cooperation proved to be the best one.

Keywords: Web caches, configuration, performance evaluation, Relais.
