看到邝总的拉斯维加斯母鸡上线了，第一时间入手了一台512MB内存的。本人的这个小站就放在他家的MC机房的服务器上。在经过半年来的使用体验后感觉不错，属于国人良心IDC。我也可喜的看到，Locvps一直在进步，目前甚至还启用了400电话做售后，规模也在不断扩大。目前我所测试的一款是基于Xen架构的512MB的VPS月付￥39.3，整体性价比非常优越（当然是在使用了优惠码40off之后）。
目前共有6处数据中心可供选择，基于销售主体都是国人用户，当然无可争议的选择了美国西海岸附近的数据中心。一律采用Xen虚拟技术，国产IDC System控制面板。
这6处数据中心如下：
拉斯维加斯、洛杉矶MC、洛杉矶PR、圣何塞、丹佛、香港
下面是目前评测的512MB内存套餐的简要测评。
配置：
512MB RAM 1024MB vSwap 2 vCPU Core 30GB Raid 10 Diskspace + BBU 500GB Bandwidth 100MB Port 1 IPv4 address XenServer IDC System
注意：VPS开通后，默认挂载10G硬盘（第一磁盘），剩下的容量（第二磁盘）就需要通过手动挂载才能扩充剩余的容量。具体挂载教程参照这里。

从追踪节点上来看，走的是he.net，而且据字面猜测，骨干网应该是10G带宽。
7、硬盘DD检测

备注：得分越高越好。可以看出，这款明显比我的那款Bandwagonhost的512MB，2核，OpenVZ的VPS的跑分结果要好。
9、其他
开通VPS用默认的root密码登录后，最好立即采用私钥方式登录并关闭SSH密码登陆。具体参照《SSH无密码登录及putty设置》
这一款用来建站或者干点什么都好，但我还没想好用来干什么。跑完我的LAMP一键安装脚本，花费时间在35分钟左右，属于正常。
本人玩VPS上瘾，属于再买剁手型，目前手中已有大大小小好几个VPS，基本都是挂个探针或者开个PPTP玩玩而已。
