I'll try that again some time.

Hmm, I don't think I have a Qt4 app with a larger model, however I do
have experience with KDE4 and at least their filesystem-model is pretty
fast. So I'm not so 100% sure its just the Qt4 model/view stuff, it may
still be related to how the models are implemented. Anyway, I'll try to
get some profiling data and see what it can tell me...
