Yes. I like how you qualify the statement. Furthermore, on the C side you have Linus and other C gurus that really, really know how to exploit the strengths of the C language.
I would also expect them to know how it works _all_ the way down through the OS, which can also have an impact on performance. IE, they know how the supporting systems operate thus can make further assumptions/optimisations.
