The Moment the Config Parser Became the Bottleneck
A real-time treasure-hunt game engine faced significant performance issues when scaling to 8,000 concurrent players. The root cause was identified as the JSON-based level loader, which became a bottleneck due to excessive runtime parsing. A switch to compile-time configuration resolved the latency issues and improved overall performance metrics significantly.
- ▪The game engine's latency increased dramatically from 22 ms to 840 ms under load.
- ▪Initial attempts to fix the issue included increasing concurrency and caching, but these only shifted the problem.
- ▪Switching to compile-time configuration eliminated the need for runtime parsing and reduced latency significantly.

The docs promised infinite scale, but at 8 000 concurrent players the Go worker pool started to stall. P99 latencies jumped from 22 ms to 840 ms in two minutes, and the k6 dashboard screamed red. The first thing we checked was CPU—flat line.
