Load test: Sample.Blazor infer endpoint

Short load test for POST /api/intent/infer (Sample.Blazor) to document p95 latency and error rate.

How the script works

The script scripts/load-test-infer.js is a k6 load test (not Node.js or Bun). It:

  1. Engine: Uses k6 (Grafana k6). Install with: brew install k6 (macOS) or see k6 installation.
  2. Target: Sends POST /api/intent/infer with a fixed JSON body: { "events": [ { "actor": "user", "action": "login" }, { "actor": "user", "action": "submit" } ] }.
  3. Load: 50 virtual users (VUs), 30 seconds, ~0.1 s sleep between iterations.
  4. Thresholds: Fails the run if error rate ≥ 5% or p95 latency ≥ 2 s.
  5. Base URL: From env K6_BASE_URL or default http://localhost:5000.

So you must have Sample.Blazor running and k6 installed before running the script.

How to run

  1. Install k6 (if needed): brew install k6.
  2. Start Sample.Blazor: dotnet run --project samples/Intentum.Sample.Blazor/Intentum.Sample.Blazor.csproj (default: http://localhost:5018).
  3. From repo root run k6: k6 run scripts/load-test-infer.js.
  4. Optional: override base URL: K6_BASE_URL=http://localhost:5001 k6 run scripts/load-test-infer.js.

Result summary (example)

Metric Target Example (run locally)
p95 latency < 2s ~XX ms
Error rate < 5% ~0%
RPS — ~XX

(Fill in after running k6 run scripts/load-test-infer.js; k6 prints summary to stdout.)

Use these numbers for production readiness and capacity planning.
