Hi,
Is this query plan the good or bad query plan or does the query plan always remain the same?
You need to include the outpout of set statistics time,io on for fast and quick (with showplan) to make an assessment.
The only obvious thing here is that it is using the single page pool in whatever cache it is using.
It may benefit from a large (8 page) i/o pool unless the dataset processed by the query is very small.
Check out infocenter.sybase.com and search for sp_poolconfig.
Cheers,
Simon
