    They’ll fix it… sounds like a skill issue, if base64 got fixed and performs better than c

      I’ve heard that while Rust has the ability to be faster than Go and maybe C, it is a lot harder to write rust code to do it

        This is not true. If you know Rust and C equally well, you’re likely go write equally performant Rust.

        You could say that Rust is harder to learn than C. I’d disagree based on my personal experience, but you wouldn’t be wrong.

    Rust running slower than C?

    Never would have guessed……

      The blind Rust hatred goes in the Phoronix comments. Rust isn’t inherently slower than C. This was a bug.

        Looks like it wasn’t even a bug, just a missed opportunity to use SIMD.

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

          Harder than C?
