Locally distributed Web server systems represent a cost-effectivesolution to the performance problems due to hightraffic volumes reaching popular Web sites. In this paper,we focus on architectures based on layer-7 Web switchesbecause they allow a much richer set of possibilities forthe Web site architecture, at the price of a scalability muchlower than that provided by a layer-4 switch. In this paper,we compare the performance of three solutions for layer-7Web switch: a two-way application-layer architecture, atwo-way kernel-based architecture, and a one-way kernel-basedarchitecture. We show quantitatively how much betterthe one-way architecture performs with respect to a two-wayscheme, even if implemented at the kernel level. Weconclude that an accurate implementation of a layer-7 Webswitch may become a viable solution to the performancerequirements of the majority of cluster-based informationsystems.
