A multi-project build is the standard in Gradle.

A multi-project build consists of one root project and one or more subprojects.
Gradle can build the root project and any number of the subprojects in a single execution.

## Comparações e velocidade

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).

Quanto mais simples o problema resolvido pela ferramenta, melhor a performance que ela terá. E a maioria dos _benchmarks_ não testam as características adicionais fornecidas pela ferramenta.
