table and index in the same tablespace


I have a table and its associated indexes all in one tablespace. Now, will creating a separate tablespace just for the indexes and drop and recreating the indexes the table has in the new tablespace  help ???  Thanks

I meant to ask if this will help in performance ?

In all probability, no.  This may have some housekeeping/ recovery benefits but it is very unlikely to have performance benefits.  Most modern disk arrays are configured so that data access is spread pretty evenly across all the spindles.  If your disk is configured such that you have "hot" and "cold" disks, and if you can move the index to a different tablespace that can be placed on one of the "cold" disks, this will tend to balance out disk I/O and may improve performance.

Thanks Justin, that makes sense
