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.
