## 性能

独立机构 TechEmpower 所作的基准测试结果显示，基于 Uvicorn 运行的 **FastAPI** 程序是 <a href="https://www.techempower.com/benchmarks/#section=test&runid=7464e520-0dc2-473d-bd34-dbdfd7e85911&hw=ph&test=query&l=zijzen-7" class="external-link" target="_blank">最快的 Python web 框架之一</a>，仅次于 Starlette 和 Uvicorn 本身（FastAPI 内部使用了它们）。(*)

**FastAPI** applications running under Uvicorn as <a href="https://www.techempower.com/benchmarks/#section=test&runid=7464e520-0dc2-473d-bd34-dbdfd7e85911&hw=ph&test=query&l=zijzen-7" class="external-link" target="_blank">one of the fastest Python frameworks available</a>, only below Starlette and Uvicorn themselves (used internally by FastAPI).
