   In the real world it's not nearly as fast as C, but in a micro-benchmark like this with a bunch of loops crunching fixed-size integers it would come close. The difference in performance between the languages is almost entirely due to d

   You can write slow code in any language, that's exactly what the problem was (and still is) here. The implementations still aren't using the same random number generator. Rust has C++ level performance if you compare the same cod
