Hi Patric

From my recent experience, you should at least try out Cetin's suggestion to use SET KEY. You can use filters as well, if needs be. Just remember that if you change the order, you need to change the set key statement to match.
If you have slow networks, the less traffic across the wire, the better will be the performance.

You will find it requires very little change to your code. Switching to SET KEY in one instance reduced the load time from over 70 seconds to about 6-7, including the time to instantiate the form, and has dramatically improved performance wherever I used it.
