Details

Use the SPDEFILECACHE system option to enable or disable file caching of opened SPD Engine data files. Caching SPD Engine data files can improve performance by reducing the need to open and close files. If SPD Engine data files are used in a shared environment, caching files can result in performance degradation. This degradation happens when a user must wait on a file that another user has opened but is no longer accessing.
