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.
specifies the number
of buffers to use for SAS data sets.
specifies the permanent
buffer size for an output SAS data set.
specifies the number
of SAS catalogs to keep open.
controls the compression
of observations in output SAS data sets.
controls when SAS log
files are opened and closed.
