Los benchmarks independientes de TechEmpower muestran aplicaciones de **FastAPI** ejecutándose bajo Uvicorn como [uno de los frameworks de Python más rápidos disponibles](https://www.techempower.com/benchmarks/#section=test&runid=7464e520-0dc2-473d-bd34-dbdfd7e85911&hw=ph&test=query&l=zijzen-7), solo por debajo de Starlette y Uvicorn en sí mismos (utilizados internamente por FastAPI).

Pero al revisar benchmarks y comparaciones, debes tener en cuenta lo siguiente.
