Re: Does the number of extents affect the performance?

Although I agree that in general having multiple extents does not affect
performance, I still think it is important to attempt to size tables
correctly as I believe for insert purposes there is an overhead in the
creation of new extents. 


Also unless I am deliberately trying to partition my data over more than
one disk I like to see a tables blocks being contiguous within a
tablespace (mainly for aesthetic reasons I'm afriad)
