Advanced Profiling
------------------

Android Studio’s Advanced Profiling feature rewrites OkHttp bytecode for instrumentation.
Unfortunately it crashes on OkHttp 4.x’s bytecode. Until [Google’s bug][advanced_profiling_bug] is
fixed you must disable advanced profiling in Android Studio.

* **Uvicorn**:
    * 具有最佳性能，因为除了服务器本身外，它没有太多额外的代码。
    * 您不会直接在 Uvicorn 中编写应用程序。这意味着您的代码至少必须包含 Starlette（或 **FastAPI**）提供的代码。如果您这样做了（即直接在 Uvicorn 中编写应用程序），最终的应用程序会和使用了框架并且最小化了应用代码和 bug 的情况具有相同的性能损耗。
    * 如果要对比与 Uvicorn 对标的服务器，请将其与 Daphne，Hypercorn，uWSGI等应用服务器进行比较。
* **Starlette**:
    * 在 Uvicorn 后使用 Starlette，性能会略有下降。实际上，Starlette 使用 Uvicorn运行。因此，由于必须执行更多的代码，它只会比 Uvicorn 更慢。

build, reporting and documentation from a central piece of information.

关键特性:

* **快速**：可与 **NodeJS** 和 **Go** 并肩的极高性能（归功于 Starlette 和 Pydantic）。[最快的 Python web 框架之一](#_11)。

* **高效编码**：提高功能开发速度约 200％ 至 300％。*
* **更少 bug**：减少约 40％ 的人为（开发者）导致错误。*
* **智能**：极佳的编辑器支持。处处皆可<abbr title="也被称为自动完成、智能感知">自动补全</abbr>，减少调试时间。
* **简单**：设计的易于使用和学习，阅读文档的时间更短。
* **简短**：使代码重复最小化。通过不同的参数声明实现丰富功能。bug 更少。
* **健壮**：生产可用级别的代码。还有自动生成的交互式文档。
