Well, as you scroll through a list of 100,000 items, it only keeps like 12 cells alive in memory. It just recycles their content. And so it has like, you know, the 10 cells that fit in the screen and it has like one above and one below. So as you partially scroll, that's already loaded. And then as you scroll the list, all it's doing is swapping in the content of those same 12 cells.
