Test de serveurs virtuels de DigitalOcean, Vultr, Linode et Hetzner. Victimes humaines: 0,0

Dans l'un des articles précédents, j'ai cité les résultats des tests de serveurs virtuels bon marché de divers hébergeurs Web. Merci à tous les commentateurs et personnes qui ont écrit des messages privés pour leurs commentaires.

Cette fois, je veux présenter les résultats des tests de serveurs virtuels de grandes entreprises bien connues: DigitalOcean , Vultr , Linode et Hetzner . 38 tests ont été effectués pour tous les emplacements disponibles.



Bien que les caractéristiques des serveurs virtuels soient cette fois très proches, il convient de rappeler que le format de test n'est pas très objectif, et les résultats doivent être considérés avec une certaine ironie, car les valeurs mesurées sont très relatives.

Comme la dernière fois, les tests ont été effectués en utilisant unixbench, dd, fio, speedtest, fonctionnant sur Debian 9, les paramètres n'ont pas changé (deux tests dd: en blocs de 64K et 1M; quatre tests fio: en lecture aléatoire, lecture directe aléatoire, modes aléatoires écriture et écriture directe aléatoire).

Il m'a semblé que les résultats les plus stables étaient ceux de Linode et Vultr. Hetzner est un peu en retard, mais il appartient à une catégorie de prix légèrement différente. DigitalOcean dans certains tests (en particulier Unixbench) était inférieur aux autres, bien qu'en général j'aime vraiment cet hébergeur.
