Here's the thing: tracing JITs can theoretically BEAT C. Why? Because a tracing JIT knows more about the system the program is running on than a compiler ever will. It knows which parts of the code are being hit the hardest. It can even inline whole inner loops across function and module boundaries.
I've heard that line of reasoning for the last 15 years. Meanwhile, a lot of brilliant people and enormous resources have been poured into trying to make it happen.
It's got a very long way to go.
