Yup. In theory Rust and Fortran perform better than the others mostly due to the strict aliasing rules. However many benchmarks won't benefit from this difference and in practice it depends mostly on the standard library implementation and the "idiomatic" solution in each language. Of course compilers matter as well and even if they can all use LLVM the maturity of the frontends does matter.
