Abstract
In this paper we describe how a profiling system can be successfully u sed to restructure the components of an operating system for improved overall performance. We discuss our choice of a profiling system and h ow if was applied to the AS/400(R) (Application System/400(R)) operati ng system for the purpose of reordering code. Previous work in the ind ustry has been mainly useful only for application programs. Our work d emonstrates how such techniques can be applied to operating system cod e, while preserving maintainability of the operating system in the cus tomer's environment.
