Inserter caching is implemented by setting the field SQL_DESC_ARRAY_SIZE on the SQLHSTMT's APD (Application Parameter Descriptor). Inserter caching is fully supported by the Microsoft SQL Server Access Library.
Reader caching is internally implemented by setting the attribute SQL_ATTR_ROW_ARRAY_SIZE on the SQLHSTMT being used. Reader caching is fully supported by the Microsoft SQL Server Access Library.
Increasing the cache parameter when producing an RWDBReader increases the number of rows fetched at a time, which can improve performance.
NOTE: Increasing the cache size may improve performance, depending on your application.
