- Add nix flake commands: bench, bench-poop, bench-quick - Add hyperfine and poop to devShell - Document benchmark results with hyperfine/poop output - Explain why Lux matches C (gcc's recursion optimization) - Add HTTP server benchmark files (C, Rust, Zig) - Add Zig versions of all benchmarks Key findings: - Lux (compiled): 28.1ms - fastest - C (gcc -O3): 29.0ms - 1.03x slower - Rust: 41.2ms - 1.47x slower - Zig: 47.0ms - 1.67x slower The performance comes from gcc's aggressive recursion-to-loop transformation, which LLVM (Rust/Zig) doesn't perform as aggressively.
