It does, but it also has the ability of generating inefficient code. Sure, it's often the developers fault but I feel like it's much easier to shoot yourself in the foot in terms of performance in C++ compared to other compiled languages.
Some real-life examples for me:
* Missing a '&' for a function parameter resulting in that object being copied for each function invocation
* Adding a couple extra chars to an error message string in an inlined function which caused that function to then be 'too large' to inline according to the compiler
