Hi Danisment Gazi Unal,

Itprof's suggestion is valid that I should be able to use an index to speed up this query.

But my objective here is to help sorting. Many users write adhoc queries to into my warehouse and all are not going to be tuned queries. Many go for full tablescans on some big fact tables and sort like hell.

We do have some good indexes for often used queries. But it is the adhoc one which people cook up that hurt us bad.

So my intention is to tune sorts. In that light could you give me an explanation for the query running slow because the sort_area_size was increased?
