The data was there already. I actually MOVED it to custom properties
rather than duplicating the data, so the overhead was no worse than it
had been and quite acceptable. The stack ended up at about 6 MB. The
data is not stored forever, it just builds up over 1 - 2 weeks, then
gets cleared and the process starts again.

I still think if you do a query and load the entire result into a
custom property, then show only portions of this data at a time in a
field, you will have the best of both worlds - minimizing the number
of trips to the server and minimizing the display times.

Cheers,
