Добрый день!
Затестил тут 2 тарифа виртуалок на хостинге Бегет. В данном посте публикую результаты теста виртуалки на самом дешевом тарифе с 2Gb ОЗУ, 2 ядрами процессора и 30Gb SSD.
Стоимость такого конфига 22 рублей в сутки или 660 рублей в месяц.
Картинки и подробности в предыдущем посте. Здесь же только данные теста.

Выводы
Неплохая VPS за свои деньги. Чем то особенным не выделяется. Каких-то косяков тоже не замечено. Вот только памяти ОЗУ кажется выделяют чуть меньше чем надо. Из-за этого тест неправильно определяет объем доступной оперативной памяти и думает что здесь нету 2 гигабайт.
