服务资产发展缓慢 [英] Serving assets is very slow in development

问题描述

我有一个standart rails 3 webapp和默认资产管道。突然之间，这些资产花费了很长时间才加载（我的页面加载速度达到〜1-2秒到〜1分钟）。服务器响应时间（/ home）是正常的，但一些.css和.js文件很长时间（最多45秒）处于待处理状态。花费这么长时间的资产只有那些由宝石提供的资产（例如： modernizr-rails / vendor / assets / javascripts / modernizr.js ）

例如，对于 modernizr.js？body = 1 ：

 请求网址：http：//dev.sharewizz.com：3000 / assets / modernizr.js？body = 1 
请求方法：GET 
状态代码：304未修改
  

统计信息：

  DNS查找5.00 s 
连接20.07 s 
发送0 
等待10 ms 
接收3 ms 
  

这是一个链轮问题吗？我怎么知道什么是错的？

注意：所有其他浏览器的行为都是一样的。 编辑：其实问题只在于chrome ，甚至没有safari。
我尝试在端口3000和端口80上使用rails s启动我的服务器（不变）

如果我访问 http：// localhost：3000 / assets / modernizr.js？body = 1 ，大部分时间是即时的，有时候会等很长时间。

config / development.rb ：

 ＃扩展加载资源的行
 config.assets.debug = false #true 
  

如果您有很多资产，每个人都花时间写入开发日志，总共添加数分钟。

I have a standart rails 3 webapp with the default asset pipeline. All of a sudden, the assets took a very long time to load (my page loads went to ~1-2secs to ~1min). The server response time (/home) is normal, but some .css and .js files are pending for very long (up to 45 seconds). The only few assets that take this long are those provided by gems (eg: modernizr-rails/vendor/assets/javascripts/modernizr.js)

For example, for modernizr.js?body=1 :

Headers:

Request URL:http://dev.sharewizz.com:3000/assets/modernizr.js?body=1
Request Method:GET
Status Code:304 Not Modified

Stats:

DNS Lookup  5.00 s
Connecting  20.07 s
Sending     0
Waiting     10 ms
Receiving   3 ms

It it a problem with sprockets ? How do I know what's wrong ?

Notes: all other browsers behave the same. Edit: Actually the problem is only with chrome, not even safari. I've tried to launch my server with rails s on port 3000 and on port 80 (no changes)

If I access http://localhost:3000/assets/modernizr.js?body=1, most of the times it is instant, sometimes it wait for very long.

解决方案

Another option - HDD isn't fast enough for logs, just bump into this (suddenly) on my dev pc. Try to set this into config/development.rb:

# Expands the lines which load the assets
config.assets.debug = false #true

If you have a lot of assets, each one take the time to write into dev log, adding up to several minutes total.
