Hmm...that's a lot of rows. I am beginning to think 3 minutes is not
that bad. A full table scan may actually be more appropriate. But how
many rows you have in the table? Not sure what you meant by "on the
outside". Best that you post the whole SQL. Did you mean
select * from (your posted SQL) where rownum < .... ?

FTS just menas Full Table Scan. You change sort_area_size from the init file or use alter session command from SQL*PLUS.
