Abstract
During the period of time from August 1970 through January 1971 and while employing the TSS/360 Time-Sharing System at this institution, it was observed by the user community that the performance of the system was poor compared to the previously used time-sharing system - the CP/67 (version 3. from Cambridge Research Center). For this reason, the problem of improving TSS/360 performance was undertaken as a thesis project. Specifically, the improvements consist of an increase in system performance - responsiveness and throughput - by judiciously adjusting the parameters of the TSS/360 Table-driven Scheduler in accordance with the Principles of Balanced-Core Time and Working Set Size. A number of test runs were made, and the result are given, employing different schedule tables. A set of benchmark programs (or script) were developed and used with these tests that were characteristic of a "typical" or "realistic" load at this institution.
