## Tests de performance et rapidité { #benchmarks-and-speed }

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).

import okhttp3.tls.internal.TlsUtil.localhost

/**
 * OkHttp is usually tested with functional tests: these use public APIs to confirm behavior against
 * MockWebServer. In cases where logic is particularly tricky, we use unit tests. This class makes
 * it easy to get sample values to use in such tests.
 *
 * This class is pretty fast and loose with default values: it attempts to provide values that are

    @Override
    public String toString() {
      return toString;
    }
  }

  /**
   * Returns a {@code Comparator<Boolean>} that sorts {@code true} before {@code false}.
   *
   * <p>This is particularly useful in Java 8+ in combination with {@code Comparator.comparing},
   * e.g. {@code Comparator.comparing(Foo::hasBar, trueFirst())}.
   *
   * @since 21.0
   */
  public static Comparator<Boolean> trueFirst() {

C’est utile pour envoyer du texte préformaté, des lignes de log, ou des valeurs <dfn title="Une valeur utilisée pour indiquer une condition ou un état particulier">« sentinelle »</dfn> spéciales comme `[DONE]`.

### 3. Compression + Encryption

Combining encryption and compression is not safe in all setups.
This is particularly so if the compression ratio of your content reveals information about it.
See [CRIME TLS](https://en.wikipedia.org/wiki/CRIME) as an example of this.

                                         TF_OutputList*, TF_Status*);

void TF_DeleteAbstractFunction(TF_AbstractFunction*);

// Register the function with the given context. This is particularly useful for
// making a function available to an eager context.
void TF_ExecutionContextRegisterFunction(TF_ExecutionContext*,
                                         TF_AbstractFunction*, TF_Status*);

The `okhttp3.internal` package is not a published API and we change it frequently without warning.
Depending on code in this package is bad and will cause you problems with any upgrade! But the 4.x
will be particularly painful to naughty developers that import from this package! We changed a lot
to take advantage of sweet Kotlin features.

#### Credentials.basic()

Et Swagger UI prend en charge ce champ particulier `examples` depuis un certain temps. Vous pouvez donc l'utiliser pour **afficher** différents **exemples dans l'interface des documents**.

Si vous utilisez des conteneurs, par exemple avec Docker ou Kubernetes, je vous en dirai plus à ce sujet dans le prochain chapitre : [FastAPI dans des conteneurs - Docker](docker.md).

En particulier, lorsque vous exécutez sur **Kubernetes**, vous ne voudrez probablement **pas** utiliser de workers et plutôt exécuter **un seul processus Uvicorn par conteneur**, mais je vous en parlerai plus en détail dans ce chapitre.

   * world. Figure out what sort of space-time tradeoff we're actually going to get here with the
   * *Map variants. This class is particularly hard to benchmark, because the benefit is not only in
   * less allocation, but also having the GC do less work to scan the heap because of fewer
   * references, which is particularly hard to quantify.
