Hi Jerry,

1.7 million rows of 30 columns each is a lot of data. The performance
might well be limited by the network capacity or by the processing that
the client does on the data.

Does the client really need all these rows? Try to refine your query -
send only those columns and those rows across the network that the
client actually needs. Pre-aggregate at the server if the client will
only use aggregates.

Best, Hugo
