A performance model of MVS

In this paper we have presented a case study of the development of a performance model for the IBM OS/VS2 MVS operating system. The purpose of the case study is to demonstrate applications of modeling techniques to real-world problems such as capacity planning and system tuning. The model is also to be used as a research vehicle for studying advanced architectural enhancements. Although further tests are being conducted with actual workloads, the initial validation results have been encouraging.
