Ditching Go for Rust: Overcoming GC Limits in High-Concurrency Game Engines

This case study highlights the critical performance ceiling of garbage-collected languages in latency-sensitive, high-throughput systems. By rewriting their event-processing hot path in Rust, the team eliminated severe GC pauses and stabilized memory consumption. It provides compelling real-world evidence that zero-allocation memory control is essential for scaling real-time applications.
