Y como puede tener paralelismo y asincronía al mismo tiempo, obtienes un mayor rendimiento que la mayoría de los frameworks de NodeJS probados y a la par con Go, que es un lenguaje compilado más cercano a C <a href="https://www.techempower.com/benchmarks/#section=data-r17&hw=ph&test=query&l=zijmkf-1" class="external-link" target="_blank">(todo gracias Starlette)</a>.

### ¿Es la concurrencia mejor que el paralelismo?

¡No! Esa no es la moraleja de la historia.

### Est-ce que la concurrence est mieux que le parallélisme ?

Nope ! C'est ça la morale de l'histoire.

And as you can have parallelism and asynchronicity at the same time, you get higher performance than most of the tested NodeJS frameworks and on par with Go, which is a compiled language closer to C <a href="https://www.techempower.com/benchmarks/#section=data-r17&hw=ph&test=query&l=zijmkf-1" class="external-link" target="_blank">(all thanks to Starlette)</a>.

### Is concurrency better than parallelism?

Nope! That's not the moral of the story.

### Ist Nebenläufigkeit besser als Parallelität?

Nein! Das ist nicht die Moral der Geschichte.
