Web server 'hello world' benchmark: Go vs. Node.js vs. Nim vs. Bun | Oct 2023

Obviously Crystal is missing here. Another benchmark: https://github.com/costajob/app-servers

Rust is mostly safety | Dec 2016

The author states: "A few valiant attempts at bringing GC into systems programming -- Modula-3, Eiffel, Sather, D, Go -- have typically cut themselves off from too many tasks due to tracing GC overhead and runtime-system incompatibility, and still failed to provide a safe concurrency model."

Nim follows a different approach.
