вы получаете производительность лучше, чем у большинства протестированных NodeJS фреймворков
и на уровне с Go, который является компилируемым языком близким к C <a href="https://www.techempower.com/benchmarks/#section=data-r17&hw=ph&test=query&l=zijmkf-1" class="external-link" target="_blank">(всё благодаря Starlette)</a>.

### Получается, конкурентность лучше параллелизма?

Нет! Мораль истории совсем не в этом.
