Why I prefer *BSD for hosting? One of the reasons, from 1,5 weeks ago:
A customer at work expected a surge in traffic, due to having a sale, on their WooCommerce-based webshop. #OpenBSD handled it like a champ, dealing with 2,51 million requests in nearly six hours time. This includes dynamic stuff like accounts and the checkout. All from a single VM (8C, 32G).
