Hands-On High Performance Programming with Qt 5

Summary

I hope you've enjoyed the journey so far. We acquired a basic understanding of the matter that we'll put to good use in future chapters of this book. Admittedly, in the second half, the discussion started to be a little low-level, going down into the inner workings of processors, but I hope you picked up at least a couple of buzzwords along the way.

So, we've arrived at the end of this chapter. Looking back, first we learned about benefits and caveats arising when we optimize performance and the pair, premature optimization and pessimization. Then, we discussed the basic rules for performance optimization, the well-known optimization techniques inferred from those rules, how and why memory access patterns matter, the way processors ...
