If and when to inline functions. 3.4 Use Caution With asm Statements in Optimized Code . Anyway my question is more general: How do I start optimizing algorithms/loops/ for_each/etc. Optimization in C & C++: good practices, pitfalls. This method uses an amount of memory that is quadratic in the number of variables to be optimized. Dynamic memory allocation and deallocation are very slow operations when compared to automatic memory allocation and deallocation. Even with g++ -O0 (yes, -O0 !), this happens. Discusses ways in which the Microsoft® Visual C++® compiler can optimize source code for speed and size and tells why code size matters. If you can observe any different the the compiler is not allowed to remove the object. This is an approximate transcript of my talk at Facebook NYC on December 4, 2012, which discusses optimization tips for C++ programs. 3.3.2 Optimization Considerations When Mixing C/C++ and Assembly 57. C++ run-time support routines obviously have a significant cost, because otherwise such behavior would have be inlined. Visual C++ supports profile-guided optimization (PGO).
