I've seen enough "performant" C++ code to disagree with your statement. If they 
knew what was going on with how C++ implemented their constructions, they could 
get a lot better performance.

The second problem with writing performant C and C++ code is the difficulty of 
refactoring code to try different data structures & algorithms. Generally, one 
picks a design up front, and never changes it because it is too hard to change it.
