Rails Development Server читает неправильные запросы "Started Get '/' ...", когда я даже не нажимаю '/'

Я сейчас занимаюсь отладкой очень медленной страницы администратора в моем приложении.Когда я читал журналы, казалось, что, возможно, был N + 1 запрос:

  Unit Load (0.3ms)  SELECT  `units`.* FROM

с десятками таких строк.

Когда я начал расследование, я удалил все, что было в моем представлении, и соответствующее действие контроллера.

rout.rb 

  # ... many other routes
  # The route causing problems  
  get '/admin/unit/:id/data/:days', to: 'admins#unit_data', as: 'unit_data'

  # You can have the root of your site routed with "root"
  root 'units#root_unit'

admins_controller.rb 

def unit_data
  puts "Hello World!"
end 

...
Hello World
  Rendered admins/unit_data.html.erb within layouts/new_application (0.0ms)
  Rendered layouts/new_application.html.erb (35.0ms)
Completed 200 OK in 744ms (Views: 45.1ms | ActiveRecord: 554.4ms)

Пока все выглядит хорошои он загружает мою пустую .erb страницу, , но после этого он по какой-то причине делает запрос в root 

Started GET "/" for ::1 at 2019-04-18 09:44:39 -0400
Processing by UnitsController#root_unit as */*

Я проверил до фильтров, но они не были реализованы для этого,Может ли это быть потенциальной причиной, почему эта страница очень медленная?Мы пытаемся оптимизировать большие объемы данных, отображаемых на графиках ... Я почти уверен, что это не имеет ничего общего с чрезвычайно долгим временем загрузки, но я все еще хочу докопаться до сути.

При отладке отдельных запросов - curl - ваш друг, потому что современные браузеры по умолчанию имеют предсказание страниц, которое может вызывать дополнительные, которые вы не ожидаете в данный момент.

Если страница требует аутентификации - вы можете "скопировать как cURL" в devtools со всеми файлами cookie и т. Д. И запросить страницу из консоли. Таким образом, вы можете быть уверены, что запрос работает только один (браузер может быть даже закрыт в данный момент)
