The performance of VM/370 systems is analyzed in relation to the multiprogramming level and the user work load. Saturation conditions are examined, and methods for locating bottlenecks in the CPU, main storage, paging, and I/O subsystems are given. The paper also describes the data requirements, along with techniques for data collection and reduction. The techniques are illustrated with data from an actual case study.
