Mais en prêtant attention aux tests de performance et aux comparaisons, il faut tenir compte de ce qu'il suit.

## Tests de performance et rapidité

Lorsque vous vérifiez les tests de performance, il est commun de voir plusieurs outils de différents types comparés comme équivalents.

En particulier, on voit Uvicorn, Starlette et FastAPI comparés (parmi de nombreux autres outils).
