0x01 前言
在gigsgigscloud香港数据中心建立之初我使用过他们的服务一段时间，总体来说是挺好的，只是带宽有点小（1m/s）并且延迟有点高，但带宽是足量的，同时价格也十分具有诱惑性。
一年后的今天我再次购买他们的服务进行测试，我购买的是位于香港数据中心的OpenVZ架构的VPS，价格极其低廉，月付2美元。
以下是我使用过的几家服务商的测试：
- 香港云服务器(VPS) – pachosting
- 新加坡服务器(VPS) – 日本GMO
- 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 控制面板
支持安装以下操作系统：
控制面板：
在控制面板中可以手动开启TUN/TAP，以前如果需要开启TUN/TAP则需要给客服发送工单，现在已经很方便了。
0x03 性能测试
服务器配置/套餐如下：
- vCPU：1核心
- 内存：512MB
- 硬盘：SAS 30GB
- IP地址：1个IPv4
- 流量：500 GB
- 网络：非中国大陆直连网络，端口速度 100Mbps
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
