      I have no idea how. I write better Rust than I do C 🤷‍♂️

      Rust and C are basically identical in terms of performance (more or less). Idk where the myth that Rust is somehow less performant than C came from.

      think it’s fair to say performance rust is hard to write

      This situation proved exactly the opposite.

      They wrote a utility to pass functional tests. It did. Then people said it was too slow. So, in just a few days or hours, they dramatically sped it up while still passing the tests.

      Seems like it was pretty easy to write fast Rust code in this case.

        Fair point. I am mostly going on what I have seen others do on streams when comparing rust and go. Go seemed faster to get good performance and rust sometimes had to write a ton of code to get the same performance.

        I don’t know if you can selectively not use Go’s garbage collector, but that seems to be the only reason Go might be theoretically slower than rust.
