最近感到Hostigation的网络越来越卡了，有时候开net speeder都没多大作用，于是又蠢蠢欲动准备搬迁。前些日子尝试了两个vps：lunanode和locvps。

lunanode是个相对较新的IDC，他们刚刚从芝加哥机房搬迁到多伦多机房，提供服务的方式类似于DigitalOcean，可以随时动态生成vps，按小时计费。不同的是lunanode是真正的KVM，而DO的KVM还没法自由更新内核。前段时间还推出了$7/month的2GB内存VPS，性价比算是挺高的了。
没有选择lunanode主要是因为两点：一是ping值太高，国内访问速度一般。到多伦多300-400ms的ping，看着实在太不爽；二是这个idc刚刚进入廉价vps市场不久，还没有证明其信誉的东西。在这个每个月都有几家idc出现几家idc跑路的时代，不得不考虑提供商信誉的问题。

尝试的另一家就是hostloc论坛的名人kwx开办的locvps，我选用的是其位于香港的机器。不得不说香港vps的响应速度实在是太让人舒服了，ssh操作如丝般顺滑，30多ms的ping，基本和国内服务器差不多，还不用纠结国内的备案。但是香港服务器也普遍有个硬伤：给的带宽太小太小！1M、2M的带宽，让人情何以堪啊。另外这家的vps跑分貌似也是不忍直视，附上晚上8、9点钟的UnixBench结果：

话说分数低得有点不正常，毕竟我在上面跑过minecraft这种耗CPU的程序，并没有感觉到任何卡顿。
总结：如果你只是想买个vps用于个人翻墙，或者随便建个小站，那么香港vps是非常好的选择。不过即使是2M带宽，看720P Youtube还是有点吃力的。对我这种习惯美国1G带宽的人来说，2M小水管无法忍受，即使我的博客平时没多少PV。

也考虑过Linode，但是之前两次冲$5送$50的活动都错过了，总觉得没占到便宜心里不爽>_<其实是我的信用卡还没批下来
最后想起来还有个新加坡的OneAsiaHost，性价比还不错。走香港PCCW线路，到国内的ping在100以内。关键是带宽给得相对较大，有100M，能满足绝大部分需求了。于是搞了个，把博客搬到了上面。顺便也跑个分：

虽然不是服务器CPU，跑分结果还是很漂亮的。
