好多已读变成未读了，强迫症患者只好再逐个帖子手动点灰掉 XD

#2 楼 @blacktulip Memcached 没法迁移，所以只能丢了

右下角赞助还是盛大云

#2 楼 @blacktulip 哈哈哈，再次丢一次，刚刚没改 Memcached 的内存...

#5 楼 @huacnlee Nooooooo…

不知道这个 vps 怎么样啊 之前晚上在家访问不了...只能翻墙来看... 北京长宽

UCloud 的华东机房是联通电信双线机房，我去联系一下 Dnspod，申请一下能否开通会员服务，帮助我们智能加速。

#11 楼 @zj0713001 #19 楼 @shooter

刚刚 UCloud 的技术人员帮我解决了联通 IP 的访问问题，我已经在 DNSPod 上开启了联通线路的双线设置。

如果你们是联通线路，那么你们 ping ruby-china.org 返回的 ip 应该是 101.69.180.25，请帮我测试一下，或者直接 ping 一下这个地址看看速度如何？

另外如果有其他地区的用户发现网络延迟很厉害或者速度很慢，请及时联系我们，我们会第一时间帮大家解决问题的。

#30 楼 @blacktulip 男默女泪。

#32 楼 @aptx4869 ab 不准，用 wrk 吧...

#30 楼 @blacktulip 刚才跟 UCloud 的人讨论了一下，表达了大部分国内用户比较 happy，英国的朋友很不 happy 这个情况，讨论后得出的结论是，八月底，他们派人去英国收拾他。

#37 楼 @lgn21st

/me hides...

其实 ping 值高问题倒不大，访问速度跟以前没什么区别。但是出现过两次发帖不成功，要刷新页面再发才行的情况。

好么，这贴也发不出了，按了「提交回复」之后按钮变成 loading 就不动了，只能刷新页面重发

#38 楼 @blacktulip 帮我继续观察。

#39 楼 @lgn21st 我的网络是有线通，我 ping ruby-china.org 时 dns 解析到了 101.69.180.25，但 ping 122.226.207.19响应更快点 (虽然差距不是很大，见 #33 楼)，怎么破？

#40 楼 @HanHor 你觉得 20 几个毫秒和 40 几个毫秒，速度真的差了有一半嘛？

#42 楼 @lgn21st 晚上回到家测试了 竟然不用翻墙就能访问了...（之前只能翻墙访问的 北京长宽）

威海网通～

#42 楼 @lgn21st 速度倒没什么影响，但连接到 ruby-china 没有达到最优啊，呵呵。我有个疑问，对于 dns 服务器来说，响应用户请求到最快的 ip 上，但实际上用户连接目标域名却没有达到最优，一般这中情况是怎么解决的呢？

#48 楼 @HanHor 可能是因为我们用的是 DNSPod 免费版的原因吧，不知道专业版是否能解决你的问题。

#49 楼 @lgn21st 哈哈，这也并非是我的需求，我最近工作上遇到了这个问题，也用的是 dnspod 免费版.。估计 DNSPod 免费版实际上还不够智能，只是简单的根据用户网络解析到对应 IP，还没达到智能解析。

Speed is better than before!
