ProWGen: a synthetic workload generation tool for simulation valuation of web proxy caches

摘要

This paper describes the design and use of a synthetic web proxy workload generator called ProWGen to investigate the sensitivity of web proxy cache replacement policies to five selected web workload characteristics. Three represen- tative cache replacement policies are considered in the simulation study: a recency-based policy called least-recently- used, a frequency-based policy called least-frequently-used-with -aging, and a size-based policy called greedy-dual-size.
