Copilot's Diagnosis: Why Go Won Where Rust Failed

GitHub Copilot's diagnosis transformed this supply chain security project by identifying that the real performance bottleneck wasn't the application logic but Rust's async model versus Go's goroutines for I/O-bound proxy workloads. This case demonstrates how AI-assisted debugging can provide expert-level architectural insights and accelerate critical technical decisions. For developers facing complex performance issues, the story underscores the importance of proper diagnosis before optimization—and how AI can guide those decisions with unprecedented speed.
