Performance Overview

Real performance in analyzing data is affected by a number of factors, from server and database configuration to the ordering of individual nodes within a stream. In general, you can obtain the best performance by doing the following:

• Store your data in a DBMS, and use SQL generation and optimization whenever possible.
• Use hardware that meets or exceeds the recommendations given in Architecture and Hardware Recommendations.
• Ensure that the client and server performance and optimization settings are properly configured. Note that when SPSS® Modeler is connected to an SPSS Modeler Server installation, the server performance and optimization settings override the client equivalents.
• Design streams for maximum performance.

More information about each of these performance factors is available in the following sections.
