In general, I would expect this to be a function of the complexity of
the query and the size of the input dataset. Because results are
lazily fetched, a simple query that just returns lots of rows should
start returning results quickly. Lots of joins and unions of large
datasets can give you problems.

Asking for distinct or sorted results for a large result set will also
be slow, because the entire result set must be materialized and
sorted. Avoid these types of queries unless you specifically need that
behavior.

How are you executing the query? If it's over RMI with a Java client
then that property may need to be set in the client.
