Abstract

This chapter studies the file caching characteristics of the industry-standard webserving benchmark SPECwev99 and develops an optimal cost model for balancing performance and disk and RAM costs, where "cost" can be very broadly defined. The model is applied to a realistic 32-bit address hardware configuration to demonstrate a solution that eliminates file accesses as potential webserving bottleneck for very high workload levels.
