Program Performance

Abstract

• Performance: Amount of memory and time to run a program. • Space Complexity: amount of memory needed to run a program. Why important? – Running in multiuser environment – Is there enough memory? – Smaller programs can be run with other programs – Estimate the largest program we can run • Time Complexity: Amount of time needed to run a program. Why important? – May need to provide a time limit. – May need to provide a real time response – Use appropriate program when several alternatives exist.
