You didn't put it "in a listbox"; you created a collection with a million entries; entries which could be anything. A "listbox" is a "visual"; it "simulates" what you think you see; it's not "real"; the collection is what's "real".

You have a collection that consumes memory based on the size of the entries; that's it. And at some point, once a collection is big enough, the system starts "paging"; and if there is not enough memory, it starts thrashing. That's where the performance, or lack thereof, comes in.


"Before entering on an understanding, I have meditated for a long time, and have foreseen what might happen. It is not genius which reveals to me suddenly, secretly, what I have to say or to do in a circumstance unexpected by other people; it is reflection, it is meditation." - Napoleon I
