Всем привет.
Возник вопрос по скорости взаимодействия обратного сервере nginx и сервера приложений puma.
Приложение написано на Ruby on Rails.
Puma отображает страничку за 30 мс, передает ее в nginx.
Nginx отдает ее в браузер за 300 мс.
Что он делает более 260 мс. Как понять в чем проблема? Как оптимизировать?
