Всем привет! Публикую тесты нескольких серверов от OVH которые я провел в октябре этого года. Все серверы для теста любезно предоставил alice2k
Публикую тест виртуального сервера от OVH на самом дешевом тарифе за 2.99 евро.
Начнем тест.
Информация о сервере
Тарифы:
Стоит отметить что это новая линейка виртуальных серверов. На странице заказа также опубликованы результаты сравнительных тестов со старой линейкой.
В прошлом году я уже тестировал сервер старой линейки. Так что мы тоже сравним =)
Из бросающегося в глаза - теперь вместо OpenVZ используется OpenStack KVM и стоимость немного выросла. Ну и традиционно они идут с AntiDDoS.
На тесте сервер с Debian 8

Выводы
Производительность VPS этой линейки выше предыдущей более чем в 2 раза. Особенно порадовал SSD вместо старого медленного SATA. Рекомендую эти сервера к применению.
