[ruby-on-rails] 느린 뷰 렌더링의 원인 진단
이것이 언제 시작되었는지 확실하지 않지만 내 앱에서 이상한 일이 발생하고 있습니다 (개발 컴퓨터에서 로컬로 실행). 갑자기 다음과 같은 메시지가 표시됩니다.
Started GET "/" for 127.0.0.1 at 2013-03-10 12:10:24 +1300

보시다시피 홈 페이지 (비교적 간단한 페이지)를로드하는 데 3 초가 걸립니다. … 우리는 하드 페이지 새로 고침을 말하는 것이 아닙니다. 다른 페이지에서 “홈”링크를 다시 클릭하기 만하면됩니다.
여기서 시작해야 할 부분이 확실하지 않지만 이것은 내 application.rb입니다.
#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
module Goodsounds
class Application < Rails::Application
config.encoding = "utf-8"
config.filter_parameters += [:password]
config.assets.initialize_on_precompile = false
config.assets.enabled = true
config.action_controller.assets_dir = "#{File.dirname(File.dirname(__FILE__))}/public"
config.assets.version = '1.0'
config.autoload_paths += Dir["#{Rails.root}/lib/modules"]
config.assets.paths += Dir["#{Rails.root}/app/assets/fonts/*"]
config.assets.precompile += %w( .svg .eot .woff .ttf )
end
end
… 그리고 dev.rb :
Goodsounds::Application.configure do
# Settings specified here will take precedence over those in config/application.rb
Paperclip.options[:command_path] = "/usr/bin/"
config.action_mailer.default_url_options = { :host => 'localhost:3000' }
config.action_mailer.raise_delivery_errors = true
# set delivery method to :smtp, :sendmail or :test
config.action_mailer.delivery_method = :smtp
# these options are only needed if you choose smtp delivery
config.action_mailer.smtp_settings = { :address => "localhost", :port => 1025 }
# In the development environment your application's code is reloaded on
# every request. This slows down response time but is perfect for development
# since you don't have to restart the web server when you make code changes.
config.cache_classes = false
# Log error messages when you accidentally call methods on nil.
config.whiny_nils = true
# Show full error reports and disable caching
config.consider_all_requests_local = true
config.action_controller.perform_caching = false
# Print deprecation notices to the Rails logger
config.active_support.deprecation = :log
# Only use best-standards-support built into browsers
config.action_dispatch.best_standards_support = :builtin
# Raise exception on mass assignment protection for Active Record models
config.active_re
cord.mass_assignment_sanitizer = :strict
# Log the query plan for queries taking more than this (works
# with SQLite, MySQL, and PostgreSQL)
config.active_record.auto_explain_threshold_in_seconds = 0.5
# Do not compress assets
config.assets.compress = false
# Expands the lines which load the assets
config.assets.debug = true

좋아, 나는 그것을 알아 냈다 (마침내). 내 실제 자산을 변경하지 않고 이제 이것이 개발임을 알 수 있습니다.

지연은 config.assets.debug = truedevelopment.rb 내부 에서 발생한 것으로 밝혀졌습니다 . 이를 설정 false하면 문제가 해결됩니다.
Rails 핵심 팀 이 기본적으로이 기능을 끄는 것에 대해 토론 했지만 아이디어에 반대하는 것 같습니다. 앞으로 나는 그들이 사용자들에게 상당한 지연 가능성을 알려주기 위해 development.rb의 코멘트 섹션에 무언가를 넣는 것을보고 싶습니다.
다음을 제안하겠습니다.
# Expands the lines which load the assets
# May cause significant delays in view rendering
좋아, 그들은 내가 중얼 거리는 것을 들었고 레일을 업데이트했다 !
답변
Rails 4.1 이상에서도 동일한 문제가 발생했습니다. Abram의 대답은 부분적으로 만 완성되었습니다.
나갈 수 config.assets.debug = true있지만 새로운 자산 확인 기능을 비활성화해야합니다.
# Adds additional error checking when serving assets at runtime.
# Checks for improperly declared sprockets dependencies.
# Raises helpful error messages.
config.assets.raise_runtime_errors = false
config.assets.debug비활성화 된 솔루션은 자산을 한 번 컴파일하고 자산을 한 번 확인하기 때문에 작동합니다. 자산 검증은 대부분의 시간을 소비하는 곳입니다.
답변
Rails 3.2.13에서 오는 경우 많은 사람들이이 문제를 경험했으며 3.2.12로 되 돌리면 해결되는 것 같습니다. github에서 더 많은 정보를 찾을 수 있습니다 .
필자의 경우 비활성화 config.assets.debug하면 약간의 속도가 빨라졌지만 3.2.12로 되 돌리면 요청 시간이 약 4 초에서 약 250ms로 감소했습니다.
답변
NewRelic.com을 살펴 보십시오 -비용이 들지만 무료 평가판을 사용하면 응용 프로그램을 완전히 분석하고 병목 현상이있는 곳을 찾을 수 있습니다.
New Relic을 제외하고는 언제 시작 되었습니까? 최근에 무엇을 바꿨나요? Rails 및 / 또는 보석을 업그레이드 했습니까? 소스 제어에서 몇 가지 이전 버전을 확인하고 실행하고 문제를 일으킨 커밋을 구체적으로 시도하고 해결하십시오.
모든 브라우저에서 문제가 발생합니까? Chrome 타임 라인 뷰어를 실행하면 브라우저가 특정 자바 스크립트 부분에서 멈춰 있는지 확인할 수 있습니다.
또한 로컬 개발 웹 서버를 씬으로 전환 해보십시오. 문제가 지속됩니까?
행운을 빕니다!
답변
OSX를 사용 중이고 .local을 통해 서비스를 제공하고 있습니까?
그렇다면 해결책으로 내 의견에서 찾은 게시물을 던질 것입니다. 하위 도메인 제약 조건 (레일 3)은 로컬 서버 (씬)를 너무
느리게 만듭니다.
