Operating System Performance.

An overview of the current and future positions with respect to operating system performance is given. While a great deal of information and a large number of models for subsystems have been developed, gaps still exist in our knowledge. Because of the severe interactions between the various subsystems of an operating system, an overall model of the total system must be developed to be able to analyze and design the performance aspects of an operating system. Although such total system designs are exceptional today, it is projected that they will become increasingly more common and necessary in the near future. Such a design philosophy will clearly have a severe impact on the way we go about modularizing operating and computer systems. [ABSTRACT FROM AUTHOR]
