In diesem Beispiel verwenden die *Pfadoperationen* unter dem `router` die benutzerdefinierte `TimedRoute`-Klasse und haben in der Response einen zusätzlichen `X-Response-Time`-Header mit der Zeit, die zum Generieren der Response benötigt wurde:

```Python hl_lines="13-20"

    We used to set this only for packages that had manual supersource. That
    worked everywhere that I know of except for one place: when running the GWT
    util.concurrent tests under Guava.

    The problem is that GWT responds poorly to two .gwt.xml files in the same
    Java package; see
