What kind of query are you using in the select, is it a straight dump of a different table, or a complex query? If it's a complex query, try
benchmarking just the select. If the select is fairly fast then you are probably having PI issues - either alot of redistribution based on the
target table PI, or alot of dupe row check if the target table has a nupi.
For the first problem, I have had success doing a fast export then fast load to the new PI. For the second problem change the table type to
multiset.
