What's interesting to note though is that I tried marking pointers __restrict__ in the performance critical sections in 2 of my C++ projects and the assembly generated by Clang was identical in all cases!

So while it is true that by default Rust has a theoretical performance advantage (compared to C/C++) because it forbids aliasing pointers I wonder (doubt) whether this will cause Rust binaries to generally run faster than C/C++ binaries.

On the other hand Rust puts security first, so there are lots of array bounds checks in Rust programs (and not all of these bounds checks can be eliminated). Personally I think this feature deteriorates the performance of Rust programs much more than you gain by forbidding aliasing pointers.

Depends on how those programs were written. Iterators should avoid bounds checking for example.
