### Testen

Öffnen Sie Ihren Browser unter <a href="http://127.0.0.1:8000/items/5?q=somequery" class="external-link" target="_blank">http://127.0.0.1:8000/items/5?q=somequery</a>.

Sie erhalten die JSON-Response:

And that's the same level of performance you get with **FastAPI**.

And as you can have parallelism and asynchronicity at the same time, you get higher performance than most of the tested NodeJS frameworks and on par with Go, which is a compiled language closer to C <a href="https://www.techempower.com/benchmarks/#section=data-r17&hw=ph&test=query&l=zijmkf-1" class="external-link" target="_blank">(all thanks to Starlette)</a>.

/// tip | Dica

É muito comum em pacotes Python tentar ao máximo **evitar alterações drásticas** em **novas versões**, mas é melhor prevenir do que remediar e instalar versões mais recentes intencionalmente e, quando possível, executar os testes para verificar se tudo está funcionando corretamente.
