I know you guys are talking about non-gui structures, but just for
comparison I included fpGUI's StringGrid results, which uses a custom
internal storage mechanism.

Creating (setting column count and row count) and populating (every cell
has a value written to it) a 5,000 x 5,000 grid takes 1.815 seconds on
my system.

The same test with a 1,000 x 1,000 takes 0.118 seconds.

The same test with 10,000 x 5,000 takes 4.514 seconds.

Not to shabby for a GUI component. ;-)

Now if any developers implements an application that actually displays
that amount of data to the end-user without filtering, I'll be first in
line to knock them over the head. :-P
