We needed to handle thousands of users. We used a popular open-source event engine. It failed.
Default settings did not work. Latency was high. Processing time was uneven. Monitoring tools showed the problem. They did not show the cause.
I read the source code. The engine failed under high concurrency. It was not built for our load.
We built a custom engine with Rust. Rust provides low-level memory management. We used a distributed architecture. Nodes handled specific events. A routing system kept it efficient.
The results were clear:
- Latency dropped from 50ms to 10ms.
- Throughput grew from 2,000 to 10,000 events per second.
- Memory use decreased.
Apply these lessons to your work:
- Read source code before production.
- Test your system under heavy load.
- Pick the right language early.
