Abstract : A set of terminal scripts and benchmarks have been derived for comparing the performance of time sharing and batch computer operating systems. Some of the problems encountered in designing valid benchmarks for comparing computer operating systems under both terminal and batch loads are discussed. The results of comparing TSS/360, CP/67 and MTS time sharing systems for the IBM 360/67 over a wide range of load conditions are presented. The results of comparing TSS, MTS and OS/MVT under batch loads are also presented. Serious performance degradation of the time sharing computer systems from overloading was experienced and a simple solution is suggested to prevent such degradation. The degradation was so severe as to render the performance less than that of a sequential job processor system. (Author)
