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。

测试的软件和手段如下:

  • ping
  • 路由追踪
  • 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

0x08 评价/价格

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。
