Software Engineering Showdown: C Vs Go Vs Rust Performance
C outperforms Go & Rust in I/O task due to simplicity & direct system access, but Rust can be optimized for better performance with buffered writer.
When you're working with a machine as powerful as an AMD Ryzen Threadripper PRO 5975WX, you expect things to move fast. With 32 cores, 64 virtual CPUs, and 251 GB of RAM, the bottleneck is rarely the hardware. It's usually the software. This experiment pits three popular systems languages — C, Go, and Rust — against each other in a simple task: writing 100,000 lines to a file. The question is, which one handles this basic I/O task better? Each language has its own strengths: C is known for its raw speed and direct system access, Go simplifies concurrency, and Rust promises memory safety withou...
