Привет!

Этот тест был проведен в августе одним из пользователей услуг данного хостера (спасибо Андрей!) и передан мне на публикацию. Итак, по тарифу это VPS с 1Gb RAM, одним доступным ядром и 20Gb SSD. Все это за 250 руб. в месяц. Цена приемлимая, на уровне конкурентов.

Тест

Тут очень краткий тест. Замеряли только sysbench’ем и dd.

Скорость записи на диск очень хорошая. Сразу видно что SSD.

Тестим проц sysbench’ем. Тут получилось чуть медленнее чем у Ihor VPS SSD Ferrum, но на уровне погрешности. Тем более как я понимаю на тестируемой VPS в момент теста также крутились сайты.

Тут такая же картина.

Разница в результатах на уровне погрешности.

Тест ОЗУ.

А вот тут практически двухкратный прирост кол-ва выполненных операций в сравнении с VPS от Ihor. Память тут работает быстрей.

А вот тут получились и вовсе странные результаты.

Более чем десятикратный прирост скорости чтения и записи судя по тесту! =)

Выводы

Жаль не было возможности потестить сеть, но кол-во выделяемых ресурсов и их качество на уровне =) Рекомендую!
