I am the maintainer of Rattletrap, a Rocket League replay parser written in Haskell.
Recently I became aware of @nickbabcock's Boxcars project, which is also a Rocket League replay parser but it's written in Rust.
I generally think of Haskell as Fast Enough ™️ for a high-level language.
I was curious to see how much faster Rust would be for this particular application.
You can see some casual benchmarks here: https://github.com/nickbabcock/boxcars/issues/6.
This Gist benchmarks four basic operations in both Haskell and Rust.
I am a Haskell programmer and want to see it triumph, but it turns out Rust is at least an order of magnitude faster in these benchmarks.
However, in the benchmark that actuall does something (the CRC benchmark), Haskell and Rust are within one millisecond of each other.
If you think there are any problems with the benchmark, please let me know.
