+# k6 Load Testing
+
+This directory is reserved for k6 load-test assets. Test scripts are intentionally not included.
+
+Place scripts under `load-testing/k6/` when needed, then run:
+
+```sh
+docker compose --profile loadtest run --rm k6 run --tag testid=gc-baseline /scripts/<script>.js
+```
+
+Defaults:
+
+- The application target for scripts is exposed as `BASE_URL=http://backend:8080`.
+- k6 metrics are remote-written to Prometheus at `http://prometheus:9090/api/v1/write`.
+- The optional k6 web dashboard export path is `/results/k6-report.html`.
+- Use a different `testid` tag for each GC tuning experiment to separate runs in Prometheus/Grafana.
