The book is primarily about Rust-specific things. Section 1 says: "Some of the techniques within are entirely Rust-specific, and some involve ideas that can be applied (often with modifications) to programs written in other languages." I will clarify this.

Having said that, Section 16 does have general optimization advice, and I will consider adding some brief notes about the things you mentioned there.

Thanks for the suggestion.
