Playing around with Rust and IO performance.
cargo run --bin single-threadOr:
cargo run --bin multi-threadsA simple way to test the app is start a server with python: python3 -m http.server 9000 , then start the app and generate some requests:
curl -i 'http://localhost:3000/'
curl -i 'http://localhost:3000/path/to/files'System information:
