Hi,

	I think that you are using this data for some calculation because I
don't belive that you whant to display them. In such situation when there
are many rows to fetch you will always have performance issues (maybe not so
big). Try to move your calculation to DB side (stored procedure or view if
feasible) where they can be significantely faster. If you need those data
for showing them then think about it once again.

Regards,
