files are treated as directives for the test's main package.
In any other context, `//go:debug` lines are ignored by the toolchain;
`go` `vet` reports such lines as misplaced.

## GODEBUG History {#history}

This section documents the GODEBUG settings introduced and removed in each major Go release
for compatibility reasons.
Packages or programs may define additional settings for internal debugging purposes;

## パフォーマンス

独立した TechEmpower のベンチマークでは、Uvicorn で動作する**FastAPI**アプリケーションが、<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">Python フレームワークの中で最も高速なものの 1 つ</a>であり、Starlette と Uvicorn（FastAPI で内部的に使用されています）にのみ下回っていると示されています。

## 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)。 (\*)
