Is anyone else seeing a big performance boost on PHP 8?

A couple of tests in my small library dealing with reflection and a bit of regexps are running 30-50% faster 💪!
It is great, but the isolated unit tests are by no means representative.

Has anyone successfully benchmarked a more complex solution already?

As the third party library support for the new PHP version is far from sufficient, I was not yet able to run more complex tests.

This is the hobby lib that's seeing the boost.

$container = new Any\Psr11\Container([
    Thing::class => new Thing()
    MyService::class => new MyService(),
]);

$callable = function (MyService $service, Thing $thing){ ... };

class Something {
    public function __construct(MyService $service, Thing $thing) { ... }
}

$g = new Dakujem\Wire\Genie($container);

// Magic! The dependencies are resolved from the container.
$value  = $g

And since the attributes can now be used instead of doc-comment annotation parsing (which requires regexp parsing most of the time), the upcoming version will be much faster by design.
