Chapter 6

1. When would you deem a simple linear search to be a justifiable choice?
   For a couple of tens of items, it is totally OK to use a linear algorithm. But be sure that you'll never have to scale this piece of code!
2. How many items do you think can be shown without problems in a standard Qt's model-view setup?
   Model-view classes will scale up to a couple of hundred items. For very big models, you have to resort to manual optimizations.
3. What could be meant by the Tower of Babel performance anti-pattern?
   That colorful name describes the situation where your program burns CPU power by constantly transforming the same data among several formats. This could be a real program in bigger systems in the enterprise programming, and you'd probably never do it in a Qt program, would you? However, I liked its name.
4. Your program suffers under a performance problem. How would...
