I benchmarked identical Go and Rust servers under heavy load: - 15,000 concurrent users - 15 minutes sustained load - Real Hetzner K3s cluster (not localhost) - Separate nodes for apps, monitoring, and load testing - k6 for load generation, Prometheus + Grafana for metrics Both servers do the same thing: 100 iterations of SHA256 hashing, return JSON. Go: standard library only Rust: Hyper + Tokio + sha2 I tracked p50, p90, p95, p99 latencies in real-time. The results were not what I expected.

Code is on GitHub if you want to run it yourself: https://github.com/huseyinbabal/benchmarks/tree/main/rust-se... Curious what you all think.
