Note that I'm not advocating bind over lambda. I'm saying that one shouldn't expect a boost in performance when switching from std::bind to lambda. Switching from std::function to a templatized "Callable" could give a boost in performance, but like I said, that's orthogonal to how the callable was created. There really is quite a difference between what std::bind returns and a type-erasing class like std::function. For the latter, the type erasure may result in a virtual call that the optimizer has a hard time seeing through. In practice, compilers are pretty good at optimizing bind. Here are some examples where lambda and bind generate identical code: https://godbolt.org/g/dQCSeG https://godbolt.org/g/dQCSeG
