While this _could_ be correct if we are just talking about Go, which has its own backend and optimizer, it is definitely not the case for Rust, which uses LLVM. The differences seen in these benchmarks are all about the gRPC implementation used; languages are irrelevant. C++, Rust, Go and Java all have their own standalone implementation written from scratch, so it's kind of an apples and oranges situation here. You can write good or crummy code in any language for what it's worth.

I agree with you and I think we're both right here, on both measures :)
