Key quotes
· 3 pulled"Premature Pessimization Easy on yourself, easy on the code: All other things being equal, notably code complexity and readability, certain efficient design patterns and coding idioms should just flow naturally from your fingertips and are no harder to write than the pessimized alternatives. This is not premature optimization; it is avoiding gratuitous pessimization." — Herb Sutter, Andrei Alexandrescu
"Back in 80s, it was possible to calculate the speed of the program just by looking at assembly."
"keep in mind that these days compilers tend to ignore inline specifications more often than not"
