That's because of model/view architecture (at least under qt) .
I think that we should think about adding TVirtualStringTree into lazarus as 
default component and use it at such critical places. There you can put 100M 
records in a msec, and also you can draw whatever there.

In my apps I'm using virtualstringtree in modules whenever I expect > 100 
items on screen, otherwise listview / stringgrid fits ok.
