Look, I need to tell you about this thing we did that honestly still kind of blows my mind — and I’m the one who built it. UDP Telemetry Firehose: When Rust on Bare Metal Outperforms Cloud by 10x Look, I need to tell you about this thing we did that honestly still kind of blows my mind — and I’m the one who built it. Raw network performance demands raw metal — understanding when to strip away abstractions for maximum throughput in high-frequency telemetry systems. 847,000 UDP packets per second from these 12,000 IoT sensors we had scattered everywhere, and our Kubernetes cluster — this thing we’d lovingly maintained for years — was just… choking. 2.3% packet loss. Which doesn’t sound like much until you realize that’s thousands of packets just vanishing into the void every second. And the latency? 200ms spikes during peak hours. Our AWS bill was $47,000 a month and climbing. Forty-seven thousand dollars.…
