我一直注意到Rails 3.1中资产管道的页面加载时间非常慢.每个资产(css / js / image)需要半秒到一秒才能加载.这真的开始阻碍发展.我在制作中没有同样的问题.
有什么解决方案吗？下面的日志文件显示了每个单独资产的加载速度为0.5 – 0.3秒： # load of page itself... ...

每当加载资产时,它必须通过Rails环境传递,Rails将重新加载所有代码.当您拥有大量资产时,它将加起来缓慢加载页面.
试试rails-dev-tweaks gem,它可以让你更好地控制Rails何时重新加载代码.应该解决你的减速问题. （编辑：李大同） 【声明】本站内容均来自网络，其相关言论仅代表作者个人观点，不代表本站立场。若无意侵犯到您的权利，请及时与联系站长删除相关内容! |
