Тестирование Дешевых Виртуальных Серверов

У многих хостеров в продаже есть дешевые виртуальные сервера, а в последнее время стали массово появляться рекламные тарифы с различными ограничениями (например, возможность заказать один такой виртуальный сервер на один аккаунт), цена которых иногда даже меньше стоимость IP-адресов.

Стало интересно провести небольшое тестирование и поделиться результатами с широкой публикой.

Часть виртуальных серверов была предоставлена хостерами ранее для одного из моих проектов, на котором я выкладываю тесты; кроме того, было приобретено определенное количество VPS по цене не более 100 рублей за штуку.

Стоит сразу отметить, что характеристики виртуальных серверов отличаются друг от друга, а производительность, измеренная в определенный момент времени, является весьма относительной величиной, зависящей от нагрузки на узел или канал, количества клиентов на узле, времени дня, средняя температура на Марсе в сезон дождей и так далее, так что материал довольно занимательный.

В качестве операционной системы выбран Debian 9, а для тестирования я использую несколько популярных программ: unixbench, dd, fio, Speedtest. С помощью dd было сделано два теста для каждой виртуальной машины: в блоках по 64К и 1М.

Утилита fio запускалась 4 раза: в режимах произвольного чтения, произвольного прямого чтения, произвольной записи и произвольной прямой записи.

Перед подведением итогов приведу краткое описание тарифов с ценами:

Итак, перейдем к тестам, а для тех, кто не хочет читать стену текста, оставлю кнопку перехода на Результаты (много графиков).

Виртуальный сервер от RUVDS:

• оборудование находится в подмосковном городе Королев (о посещении этого дата-центра я уже писал ранее );
• Дешевый тариф (10 ГБ SSD/1x 2 ГГц CPU/0,5 ГБ RAM/100 Мбит/с за 30 рублей в месяц)
• на данный момент хостер все еще борется с эффектом хабра, а данный тариф доступен только по предзаказу;
• Существует ограничение на один такой VPS на аккаунт.
