summary

Ktor app compiles to a Linux executable with Kotlin Native, is dockerized and runs on Kubernetes, using SQLDelight + Postgres and Arrow for the demo, and load tests use the dosify CLI. Result: container image is about one third the JVM size, startup hits ~2s vs 4s for JVM, memory and CPU are significantly lower and performance is instant with no warm‑up, whereas JVM warms up and reaches ~20× better latency after many requests.
