As an experienced programmer,
you want your SAS programs to obtain the desired results while minimizing
the use of resources such as CPU time, real time, memory, and I/O. It
is particularly important to optimize your SAS programs if you write
or maintain production programs and work with large data sets. However,
before you can select the most efficient programming technique to
perform a particular task, you must carefully consider the technical
environment and the resource constraints at your site. There is no
single set of programming techniques that is most efficient in all
situations. Instead, trade-offs in resource usage are associated with
each technique.
In this chapter you
learn about analyzing the requirements for efficiency at your site
and about running benchmarks to select the most efficient SAS programming
techniques.
Note: This chapter has no quiz.
