Pooling is a feature of SAS clients that increases the efficiency of connections to SAS. Pooling is only available for SAS Workspace Servers. When a SAS client application is configured to access a pooled workspace server, the client application maintains a collection of reusable workspace server processes called a pool. By reusing server processes, pooling avoids the processing that is associated with creating a new process for each connection. If your client application uses frequent, quick connections to SAS, pooling might greatly improve your server performance.
