Привет!
Еще в январе-феврале 2016 года я регал вируталки и запускал на них тесты. И только сейчас дошли руки запостить результаты.
Сегодня у нас на тесте виртуалка на OpenVZ на самом минимальном тарифе за 249 руб. в месяц (1 ядро, 1Gb RAM, 20Gb SSD).
Накатил CentOS 6.7

Дали вот такое одно ядро от процессора E5-2620:

Тут openvz выдает старое ядро 2.6.32. Объем дискового пространства inxi почему то отказался показывать)
Кстати вот и оно:

Да, сразу видно что это Москва. В среднем результат около 30мс, но не всегда стабильно почему то.
dd показал какие то уж совсем космические скорости записи на диск. Интересно, что это? Хитрое кэширование? )

Вполне нормальное предложение с ценами средними по рынку. Если вам нужен недорогой виртуальный сервер с расположением в Москве то думаю стоит рассмотреть этот сервис.
