How to Speedup datareports....

Hi,

I'm working on a project, that has to work over a WAN, and some sites of our company has very bad connections. I've wrote a 2 programs, one for the server, and one client-program. I use also MessageQueues, and this works good. The response-times are acceptable.

Now I have to build in reports, and therefore I use DataReports. When I use these over the LAN, there is no problem, the response-time is acceptable, but when I open this DataReport over the WAN, I've got very slow response-times.
Is there a way to speed this up, or is there a way to fill the DataReports manually...?
I make a connection to an SQL server, and I use Server CursorLocation...

If you need more info, don't hessitate to ask me...
