QGraphicsView performance

Message 1 in thread

I've been using Qt4's QGraphicsView for a few months, and I've read 
various comments on its performance. I'm not terribly impressed with its 
performance mysekf, but I very much like the API for selection, 
collisions, and fancy painting features like anti-aliasing. Anyway, I've 
written a small tutorial on how to make it perform a little bit faster, 
and I was wondering if anyone here has any feedback or criticism. Here 
it is:
