> n practice, Go can typically outperform Rust in throughput (using more memory), despite having a mountain of disadvantages against it in theory

This is a huge claim that disagrees with both my real-world experience and everything I've seen from artificial comparisons.

Every high performance Go system I've worked on has quickly reached the point where we're optimizing memory management and doing things that would have been explicit in a non-GC language like Rust anyway.

The Go runtime is amazingly optimized, but it comes with overhead over doing the same work directly in a lower level language.

Go has few issues with performance (lack of in-line union types, interface overuse, inefficient idioms reg. collections, some missed optimizations) but its seems plausible for a idiomatic Go program to outperform an idiomatic rust program in some situations.
