Si vienes de otro framework async que no funciona de la manera descrita anteriormente y estás acostumbrado a definir funciones de *path operation* solo de cómputo trivial con `def` normal para una pequeña ganancia de rendimiento (alrededor de 100 nanosegundos), ten en cuenta que en **FastAPI** el efecto sería bastante opuesto. En estos casos, es mejor usar `async def` a menos que tus *path operation functions* usen...
