Other zero-abstraction languages like Rust and Ada have comparable performance to C/C++. Fortran in particular, which has a lot of high performance code written in it, is sometimes faster than C due to optimization assumptions the compiler can make about Fortran code that it can’t about C code. Julia can be slower than these languages due to having a garbage collector and not being a statically compiled zero abstraction language (though it is designed to dynamically compile to overhead-free code), but for some tasks it can actually be way faster than normal implementations in C or assembly, due to its ability to dynamically compile code specific to the particular invocation of a function.
