Я не впевнений, коли це почалося, але в моєму додатку відбувається щось незвичне (запускається локально на машині розробки). Раптом я бачу такі повідомлення, як:
Started GET "/" for 127.0.0.1 at 2013-03-10 12:10:24 +1300

Як ви можете бачити 3 секунди для завантаження домашньої сторінки (порівняно проста сторінка) ... Ми не говоримо про жорстке перезавантаження сторінки .. просто ще раз клацніть на посилання "домашня сторінка" з іншої сторінки.
Не дуже впевнений, з чого тут почати, але це мій application.rb:
#config/boot.rb is loaded
require File.expand_path('../boot', __FILE__)
require 'rails/all'
if defined?(Bundler)
Bundler.require(*Rails.groups(:assets => %w(development test)))
end

config.assets.paths += Dir["#{Rails.root}/app/assets/fonts/*"]
config.assets.precompile += %w( .svg .eot .woff .ttf )
end
end
... та dev.rb:

Добре, ось що я бачу на новій реліквії. Мені це насправді не допомагає. Будь-які думки?

До речі, я вимкнув самоцвіт quiet_assets, щоб побачити, що я можу виявити в терміналі .. ще раз .. не корисно:
