#12 楼 @hooopo 而且也不是这么好移动的，依赖了很多 Rails Helper，另外到时候格式化规则改变，就数据无法更新，只能上局部缓存了。

刚刚测试，目前查看帖子页面最耗时的就是 format_topic_body 这个转换过程，比如 777 这片 58 个回复，如果不用 format_topic_body 的话，Rendered topics/_replies.html.erb 的时间可以从 (252.6ms) 下降到 60ms，这个数字还是很可观的。 需要做的就是把 format_topic_body 的过程放到数据提交的时候，查出来就是有格式的。

#6 楼 @hooopo 不过两种方式效果看起来是一样的，只不过简化了一下，执行时间是差不多的。

#6 楼 @hooopo 原来 Rails 3 还有这个东西，才知道。 http://rails.rubyonrails.org/classes/ActionView/Partials.html

<%= render :partial => "replies/reply", :collection => replies%>

replies/reply.html.erb

第 <%= reply_counter + 1 %>楼, 创建于 <%= reply.created_at %>

#3 楼 @hooopo 什么 : collection ?

似乎 MongoIC 依然不给力，刚刚有几个请求：

Completed 200 OK in 842ms (Views: 162.0ms | Mongo: 677.9ms | Solr: 0.0ms)
Completed 200 OK in 948ms (Views: 95.1ms | Mongo: 851.6ms | Solr: 0.0ms)

做个标记，以后调整哪来对比 1 CPU, 1G 内存，4 个 unicorn 进程，帖子 1000 用户 1000 现在的响应速度

帖子查看页面，以 777 这篇为例，目前有 58 个回复

#7 楼 @xds2000 不喜欢用 unless 容易逻辑混乱 if ! 比较符合语言说法，“如果，如果没有”

你试试 rvm use 1.9.3

看不明白 你 RVM 是如何安装的，ruby 是如何安装的？ 另外别贴图啊，可以直接复制发上来

#5 楼 @ery 谢谢提醒 这个时期可以呼唤 @zhuangbiaowei 报告上去

#16 楼 @ichord 现在没这么多资源 另外这个是老贴了，现在在 VPS 上面跑的，一直很稳定。

一直想买个 Air，但是由于败了很多钱在电子产品上面，老婆不让...

我是一直不习惯用分屏

http://ruby-china.org/users/location/广州 http://ruby-china.org/users/location/深圳 这里可以看到有很多啊！

额，中文无法加链接。

#7 楼 @HungYuHei 哈哈哈，大家想法都一样

#3 楼 @fsword 用来不用那个功能，都是用 http://rdoc.info 代替的。

#9 楼 @bindiry 可以给他提交个修正啊

发帖时候那个 Connection refused - connect(2) 是由于 solr 没有启动，用 rake sunspot:solr:start

用 RVM 快速安装这个补丁

rvm remove 1.9.3
rvm get head
rvm install 1.9.3 --patch falcon
rvm 1.9.3 --default

下面是最近一个月的情况：

Mac，买了 ThinkPad 你一定后悔

@hayeah 的工作方式让人无比羡慕啊！

#25 楼 @hayeah 不会的

昨日达到了 9K 的 PV

#18 楼 @liuhui998 现在 4%

@jinleileiking 那也不行，有时候有好几个不错的回复

@jinleileiking @lainuo vote 的数量不好控制，如果设置 10，长久下去终有一天会到 10 的。

改了一下说明，让你们误解了，看帖子内容。
