Home -> Community -> Mailing Lists -> Oracle-L -> Re: separate tablespaces for tables and indexes
That is precisely the point I can still remember from Oracle university classes I took in 1998 on Oracle 8.

Hi Tom,
Separating Tables from Indexes is good for managing different types of objects.
How would separating them enhance performance?
In a multi-user system with several sessions selecting, inserting, deleting and modifying data, separating the indexes from the tables would not seem to have any performance benefit.
Even if there is only one user on the system, indexes must be read before the table is read ( if the table is read at all). They aren't actually in contention.
