HostnameTrait::lower() is pretty slow, because it's currently doing a lot of work to lowercase only ASCII characters. Running this script through Blackfire locally, I get a 9% speed boost (2.51s vs 2.29s when run using
blackfire run --samples=5 php perf.php) after applying the following change. I don't see any downsides, and it still passes all tests.
