在 MAC 上搭建了一个,每打开一个页面差不多得 2 秒钟,都花费再 erb 模板渲染上了,production 环境应该也改善不了多少吧,erb 模板没法缓存。

下面是打开首页时 console 的信息:

development 上 deface 很慢,production 好一些。

生产环境没这么慢,都有 cache 的。

### 开发模式
Completed 200 OK in 2323ms (Views: 2284.9ms | ActiveRecord: 19.6ms)

###生产模式
Completed 200 OK in 33ms (Views: 17.1ms | ActiveRecord: 7.2ms)

这是我机器上同一个页面的在生产模式和开发模式下的速度差异。基本不用担心。

另外把 development 的 config.assets.debug 设为 false,也能提升一点速度。

#3 楼 @beiersi 咦?生产模式的 views 是怎么提速的?我记得 erb 模板没缓存的,slim 模板有缓存

#5 楼 @tini8 生产模式下启用了 cache 的,fragment cache。

#5 楼 @tini8 #6 楼 @beiersi 生产模式可以跑下面命令预编译 deface 替换的模板,这个才是提速的关键。

rake deface:precompile
