System performance effected by additional memory

Abstract

The University of Mississippi instal~ ed a DEC-1077. This system contains dual central processing units (CPU), version KI-10, with 192K words of core memory in 1973. At installation time, we had two (2) RJE stations and 40 TTY's; the workload was about 60% saturation. Our computer users seemed to be happy. With increa~ ing enrollment on the campus, workload also raised 15-20% yearly. Two RJE and 40 TTY's were added to this system. Consequently, we reached our saturation for CPU cycles. We are looking for some hardware or software to improve our throughput and response time.
