You could be getting thrown off by the behavior of the server. It could be
churning through the dataset on the server and buffering up records and then
when a network packet is filled it will send a batch of records to be
fetched. If your dataset is small then it will seem like it spent a whole
bunch of time to get the first record when in fact the lag was for the
server to prepare all the records.
