System tuning: performance optimization
J. G. Downward · OSTI OAI (U.S. Department of Energy Office of Scientific and Technical Information) · 1981
Anyone who has done an RSX11M SYSGEN invariably wonders what real effect the various performance SYSGEN options have. Once one has a running system, soon one starts wondering if there are any other ways to improve the system's overall performance or functionality. This session will attempt to address these issues. Topics to be discussed by the panelists will include: how to define performance. How to measure it. Performance measurement tools; SYSGEN options. Setting executive timesharing intervals. QIO optimization. choice of F11ACP. Useful tricks; POOL: (a) minimizing POOL fragmentation; (b) decreasing POOL requirements; use of resident libraries; optimizing disk usage and access times; measuring system disk loading; improving program execution times; optimizing small/big system performance; optimizing a system for: (a) program development; (b) real time work.
