Improving Performance of SAS Applications

SAS offers tools to control the use of memory and other computer resources. Most SAS

applications run efficiently in your operating environment without using these features.

However, if you develop applications under the following circumstances, you might

want to experiment with tuning performance:

• You work with large data sets.

• You create production jobs that run repeatedly.

• You are responsible for establishing performance guidelines for a data center.

• You do interactive queries on large SAS data sets using SAS/FSP software.

For information about improving performance, see Chapter 12, “Optimizing System

Performance,” on page 195.

Moving SAS Files between Operating

Environments

The procedures for moving SAS files from one operating environment to another vary

according to your operating environment, the member type and version of the SAS files

that you want to move, and the methods that you have available for moving the files.

For details about this subject, see Moving and Accessing SAS Files.
