  * “kubectl run” now produces Deployments (instead of ReplicationControllers) and
Jobs (instead of Pods) by default.
  * Pods can now consume Secret data in environment variables and inject those
environment variables into a container’s command-line args.
  * Stable version of Heapster which scales up to 1000 nodes: more metrics, reduced

そして、それは**FastAPI**で得られるパフォーマンスと同じレベルです。

また、並列処理と非同期処理を同時に実行できるため、テスト済みのほとんどのNodeJSフレームワークよりも高く、Goと同等のパフォーマンスが得られます。Goは、Cに近いコンパイル言語です <a href="https://www.techempower.com/benchmarks/#section=data-r17&hw=ph&test=query&l=zijmkf-1" class="external-link" target="_blank">(Starletteに感謝します)</a>。

### 並行は並列よりも優れていますか？

いや！それはこの話の教訓ではありません。
