## Tests de performance et rapidité

Lorsque vous vérifiez les tests de performance, il est commun de voir plusieurs outils de différents types comparés comme équivalents.

En particulier, on voit Uvicorn, Starlette et FastAPI comparés (parmi de nombreux autres outils).

            // first one is known, so it comes first
            return -1;
        }
        int rv = Integer.compare(i1, i2);
        if (rv != 0) {
            return rv;
        }
        // same execution point, now compare priorities
        return Integer.compare(p1.priority(), p2.priority());
    }

 The jar file is executable and provides a little tool to display how Maven parses and compares versions:

+----+
$ java -jar maven-artifact-*.jar 3.2.4-alpha-1 3.2.4-SNAPSHOT 3.2.4.0
Display parameters as parsed by Maven (in canonical form) and comparison result:
1. 3.2.4-alpha-1 == 3.2.4.alpha.1
