Привет!
Затестил новые виртуалки от VDSina. На этот раз это VDS с процессором AMD Epyc. Обычно я беру виртуалки на процессорах Intel. Посмотрим теперь на AMD =)
Панель управления сервером в VDSina
Если сравнивать с функционалом панели образца 2018 года то есть небольшие изменения. Но в целом все точно такое же.
Пункты с изменениями
Новые тарифы и образы ОС
Появилась возможность настраивать локальную сеть между серверами.
Вместо “Снимков” за 15 рублей/день теперь можно создавать до 1000 резервных копий по 1,5 рубля в день за 15 гигабайтный диск.
Пункты без изменений.
Управление сервером
Смена пароля и VNC-доступ
Переустановка ОС
Заказ дополнительных IP
Можно переключить тариф, но только в бОльшую сторону.
Панель мониторинга нагрузки не изменилась.
Сведения о VM
На сервере установлена CentOS 7.8

Выводы
Тут честно даже и не знаю что сказать. На каких-то операциях процессор от AMD показал себя сильно производительнее процессора от Intel, а на каких-то показал результаты ниже.
В целом это достаточно производительная виртуалка за 300 рублей. Я считаю что можно смело брать.
