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 тарифе VPS SSD 2 за 5.99 евро.
Начнем тест.
Информация о сервере
Тарифы:
Здесь все аналогично предыдущему тесту. Разница только в том что тариф подороже.
На тесте сервер с Debian 7
