Here are the differences between a standard workspace server, pooled workspace server, and load balanced workspace server:
In the default configuration, SAS presents you with a workspace server that is not pooled (standard workspace server) and a workspace server that is pooled (pooled workspace server).
For the standard, non-pooled workspace server, SAS creates a new server process each time that a client requests a connection. For simple configurations and for sites that do not place heavy loads on a workspace server, a non-pooled server might be adequate. In situations where the demands on the workspace server are greater, you should (depending on which SAS application you are using) consider configuring the workspace server for either pooling (web applications) or load balancing (desktop applications).
In a pooling configuration, a set of server processes are reused to avoid the processing time that is associated with starting a new process for each connection. SAS offers two types of pooling: client-based and server-based. A pooling configuration can also be shared across multiple machines. Pooling is recommended if your server supports SAS Web Report Studio and other web applications. For more information, see Overview of Pooling.
In a load-balancing configuration, your workspace server processes are distributed between multiple machines. Load balancing is recommended if your server supports applications that submit large jobs, such as SAS Data Integration Studio. For more information, see Overview of Load Balancing.
