Приветствую!
Сегодня очень короткий тест сервиса от AdminVPS. Сервис ощутимо дороже своих конкурентов, но этому есть ряд причин. Во-первых они позиционируют себя как сервис по программе все включено, а во-вторых размещаются в ДЦ Caravan и заявляют что совсем не оверселят. Публикую тест который делал в начале 2016 года.
По какой-то причине я выбрал не самый минимальный тариф - Start (1 ядро, 1Gb RAM, 10Gb SSD) на OpenVZ за 1000 рублей в месяц. ОС CentOS 7.0
[root@tst ~]# inxi -b

Итак, нам дают 1 ядро процессора E5-2630:

Выводы
Предложение больше подойдет для тех клиентов которые не хотят/не умеют администрировать свой сервер и хотят получить полный комплекс услуг с адекватной техподдержкой. В остальном же - предложение ощутимо дороже аналогов.
