Which is not at all surprising. Rust has much larger compilation unit and knows more about what can read/write a particular piece of memory. This allows some occasions for optimization where C compiler must be conservative. An example of simpler version of this is Fortran that can be faster for numerical loads due to the fact that Fortran disallows aliasing of function arguments. C on the other hand, must pay the price of having to be conservative with how it treats arguments just in case they overlap.
