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）。(*)

## 可选依赖

用于 Pydantic：

import java.util.concurrent.ConcurrentHashMap;
import java.util.concurrent.ConcurrentMap;
import java.util.concurrent.ConcurrentSkipListMap;
import org.jspecify.annotations.NullUnmarked;

/**
 * Helper classes for various benchmarks.

 * @author Christopher Swenson
 */
@NullUnmarked
final class BenchmarkHelpers {
  /** So far, this is the best way to test various implementations of {@link Set} subclasses. */

## 效能

來自獨立機構 TechEmpower 的測試結果，顯示在 Uvicorn 執行下的 **FastAPI** 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 框架之一</a>， 僅次於 Starlette 和 Uvicorn 本身 (兩者是 FastAPI 的底層)。 (\*)
