Simulated environment for performance
I know that C++ is the language of choice when performance is critical, when speed is a must. That's why it is used in many bank systems, embedded devices, and in many applications of Facebook back end.
Every book you read on C++, performance is emphasized and you learn how to achieve the best performance. Recently I've been studying move semantics.
The problem I have (not an actual problem, more like a curiosity) is that there's no way I can witness the performance boost in my machine.
My laptop is a i5-7300 2.5GHz and I don't feel no difference if I implement move semantic in my code or not for example.
So I am wondering if there's no simulated environment where I can see the C++ actually working its 'magic'. Where depending on the coding I see the performance difference clearly (runs fast or not)/

About the move vs copy speed comparison have a look at this post on SO.

Yeah, many books forget to mention that there are other important things like testability, correctness, maintainability
