WorkSpace settings
Workspace settings specify the location (file or memory) of the workspace and PageSize and PageCount settings for configuring the page size. Workspace settings allow you to optimize the speed of map processing.
When a map is run, a paging scheme to access information about the data as efficiently as possible is used. Portions of both working data and actual data are paged, as needed. The workspace can be a combination of files and memory, or simply memory-based. When file-based workspace is used, the amount of memory accessed at a given time depends on the number of pages and the count of pages configured for a map to run.
The Workspace settings specify the location (file or memory) of the workspace and Page Size and Page_Count settings for configuring the page size.
