I am running a data warehouse using Oracle 8.1.6
Assuming that I have 80 gig of data
in one table. I have a very fine tuned
select statement that returns the result I want in
30 minutes from one particular select statement.
If the data in the table grows 2 folds to 160 gig.
Do you think that that same query will take 60
minutes to return the output?
NOTE: The query is very fine tuned in the best
possible way. And the select statement has not
being altered/changed.

It depends on way too many variables to guess.
If it is a simple tablescan, then probably
If it is a simple index lookup, then probably not.
If it is a join of multiple tables with tables scans and indexes and has joins and nested loops where some percentage of the blocks might be cached, then flip a coin and make a guess.
