SOME CASE STUDIES OF PEHFOHMANCE

General
This section is designed to present a general guide
to the principles involved in improving performance.
It
also shows many of the techniques used to fit a
large problem into core, stressing how to do so
without adversely affecting performance.
In
order to best illustrate these principles, three
case studies, or sample problems, are shown in de-
tail:
• Case I -- a commercial job, typical of a
payroll-type application
• Case II -- a commercial job, typical of an
accounting type application
• Case III -- a scientific or technical job, in-
volving mostly computation, with little or no input!
output
All examples are based on an 8K 1130 system,
but the principles are the same for any size machine.
