This chapter demonstrates
using SAS best programming practices to optimize performance. As
you compare the techniques that are described in this chapter, remember
that differences in the use of resources are affected by the operating
environment you work in and by the characteristics of your data.
Each topic includes
examples that can improve program efficiency. Write programs to generate
your own benchmarks, and adopt the programming techniques that produce
the most savings for you.
Note: This chapter does not cover
the SAS Scalable Performance Data Engine (SAS SPD Engine), which is
a SAS 9.1 technology for threaded processing. For details about using
the SAS SPD Engine to improve performance, see the SAS documentation.
