Out of curiosity, what makes QDataStream slow? From your other comment
on QBuffer, it sounds like it might be related to the QIODevice
interface. Does that mean it's impossible to get best performance
through QIODevice, because of some design flaw? Or is there something
else that makes QDataStream and QBuffer slow?
