All Operating Environments: Setting SAS System Performance and Logging Options

Several SAS system options can help you reduce the number of disk accesses that are needed for SAS files and, therefore, enhance system performance. The SAS system options that are listed here are valid for all operating environments. Options that are operating environment-specific are documented in the sections that follow.
From a SAS session, run PROC OPTIONS to find the default settings for SAS system options on your operating environment.
BUFNO=
specifies the number of buffers to use for SAS data sets.
BUFSIZE=
specifies the permanent buffer size for an output SAS data set.
CATCACHE=
specifies the number of SAS catalogs to keep open.
COMPRESS=
controls the compression of observations in output SAS data sets.
LOGPARM=
controls when SAS log files are opened and closed.
