Introduction to Optimizing Performance

SAS software includes many features that can help you manage CPU, memory, and I/O resources effectively. The following sections describe features that are either specific to z/OS or that have characteristics that are specific to z/OS. The information is applicable to your site whether you run SAS interactively or in batch mode.
For additional information about optimizing SAS performance under z/OS, see Tuning SAS(R) Applications in the OS/390 and z/OS Environments, by Michael Raithel (available through SAS as part of the Books by Users program).
For information about optimizing SAS performance on any host operating system, see SAS Language Reference: Concepts and SAS(R) Programming Tips: A Guide to Efficient SAS(R) Processing.
