It depends on your platform. If you're running a Netware server version, it may not make any difference. On Mainframes, if you create your table and index tablespaces on different disk devices, you can get some advantage. If you distribute the work over two devices, then it speeds up the process. (You'll have to check with your SysOp for file/member names to use in the CREATE TABLESPACE statement.)
Good Luck!
