Until now I didn't have to take care about really low-speed
connections, since all my apps were used in LAN environment with
10/100Mbps or higher speed connections.

I use FB1.5, IBX and Delphi 7.

Usually I use TIBSQL as fastest way to send/get data.
However, if I have to get a query with result including e.g. 1000
records, getting all of them and iterating through result set can take
too much time (on my 'new' testing environment with speed of 7kB/s,
almost 8 seconds for getting 1000 rows with only two fields - one
varchar and one integer).

First version used IBQuery connected to TDBGrid, but I decided to go
with IBSQL and simple ListBox or similar component. With IBQuery
(which is, as much I understand scrolled when necessary) results were
displayed quicker, but other functions (e.g. selecting item and
getting additional data from database) were slower - perhaps because
IBQuery makes 'scrolling' during selection or something like that... I
am not sure.

I believe, best solution would be partial fetch of result records
(with FIRST/SKIP).

Are there any developers working in similar low-speed environemnts?
Any results or ideas you would like to share it?
