Wahou !! Thank you @OvermindDL1 !! Amazing answer. I know my comparison was kind of stupid (not real benchmark + based on time etc …) but that was just a quick check and I got really surprised by the results. Don’t know about Rust but for Go the binary is fat because it includes the entire runtime (run your binary on another machine that doesn’t know anything about Go, it will run 🙃, if same OS and arch).
