If a synchronizing read-like memory operation <i>r</i>
observes a synchronizing write-like memory operation <i>w</i>
(that is, if <i>W</i>(<i>r</i>) = <i>w</i>),
then <i>w</i> is synchronized before <i>r</i>.
Informally, the synchronized before relation is a subset of the implied total order
mentioned in the previous paragraph,
limited to the information that <i>W</i> directly observes.

Mas quando se checa _benchmarks_ e comparações você deveria ter o seguinte em mente.

## Benchmarks e velocidade { #benchmarks-and-speed }

Ao verificar os _benchmarks_, é comum observar algumas ferramentas de diferentes tipos comparadas como equivalentes.

Especificamente, observa-se Uvicorn, Starlette e FastAPI comparados juntos (entre muitas outras ferramentas).

Al agregar una estrella, otros usuarios podrán encontrarlo más fácilmente y ver que ya ha sido útil para otros.

Escreva instruções `assert` simples com as expressões Python padrão que você precisa verificar (novamente, `pytest` padrão).

/// tip | Dica

Observe que as funções de teste são `def` normais, não `async def`.

E as chamadas para o cliente também são chamadas normais, não usando `await`.

Isso permite que você use `pytest` diretamente sem complicações.
