Performance of Zig vs Rust vs C

Performance of Zig vs Rust vs C

Things to know

My CPU is a Amd Ryzen 9 7950x, so results may vary a lot on other CPUs.
My Rust binary is still pretty small compared to normal Rust binaries, check the Cargo.toml file for more info.
The C and Rust binaries are dynamically linked, and the Zig binary is statically linked.
