0x01 前言
昨天我写了一篇香港PacHosting VPS的评测文章（请点击这里查看评测），今天补上另一家我觉得合适建站的服务商的VPS。来自日本GMO财团的新加坡机房，价格比香港的PacHosting便宜，虽然性能比香港的PacHosting稍逊色，但价格却比PacHosting更为诱惑。
而尝试过那么多家VPS服务商后，我只推荐以下两家，价格适中，网络速度和硬件性能也都能满足基本需求：

美国hostus云服务器测试：
美国Hostus云服务器(VPS) – OpenVZ 达拉斯数据中心
美国Hostus云服务器(VPS) – KVM & OpenVZ LAX02数据中心
0x02 服务器信息/性能测试
服务器配置/套餐如下：
- vCPU：2核心
- 内存：1GB
- 硬盘：SSD 50GB
- IP地址：1个IPv4
- 网络：100M。但不能长时间占用超过40M的带宽，要不然会被限速至256K（32k/s）！长时间是多少？我也不知道，但我试过连续4小时以50M（约6.25m/s）的带宽下载文件。紧接着就被限速了。24小时后解除限速。

- wget测速
- speedtest测速
- 基于dd的硬盘IO测试
- 基于fio的硬盘IO测试
- 基于RAMSpeed/SMP的内存测试
- 基于UnixBench的系统基准测试

我看好的这两家服务商的VPS各有优势。其中香港的网络状况要比所有国外的都要好，甚至性价比比国内同配置的主机要高。但价格与国外的主机相比却是毫无优势。但一分钱一分货，要好又要便宜的东西可是不存在的哦！
至于日本GMO的新加坡主机，一切都是那么完美，而网络却是完美中的一颗瑕疵。再次提醒：不能长时间占用超过40M的带宽，要不然会被限速至256K（32k/s）！长时间是多少？我也不知道，但我试过连续4小时以50M（约6.25m/s）的带宽下载文件。紧接着就被限速了。约24小时后解除限速。
过些天我再写篇文章，说说怎样从上面的数值得出有用的信息。说实话，其中很多的信息我也不懂，给我点时间翻书。有其他问题欢迎给我留言或通过邮件与我取得联系。
