引子
很多人在困惑到底选择买哪家的VPS，我们都希望买低价质优的，然而没用过，就没有发言权，西蒙宫刚好手上有这三家厂商的VPS因此用来做个测评，希望对各位看官有所帮助。
简介
我所购买的套餐：
搬瓦工：年付9.99美元，内存512M，硬盘5G，5G promo 。OpenVZ架构
DigitalOcean：月付5美元，内存512M，硬盘20G，总之是目前DigitalOcean家最便宜的套餐。KVM架构
Virmach：年付12美元（黑色星期五优惠购买），内存2G，双核，硬盘25G，性价比很高。OpenVZ架构（最新Virmach的促销信息分享：Virmach优惠分享2016年12月圣诞——最低3美元/年）
测试方法
前人已经造好了轮子：bench.sh
wget -qO- bench.sh | bash

总结
测试结果可以用数据来说明这三家服务商的优劣，
搬瓦工（bandwagonhost）的CPU性能强劲，对香港的CN线路网络较好，SSD硬盘读写速度很快，其搞促销的活动较少，但月付2刀，不满意还可以退款，已经是非常良心厂商咯；
DigitalOcean家的网络较好，各方面都很平均，而且架构也很好，不易超售，没什么亮点；
Virmach当之无愧是性价比之王（促销时），年付12美元（这种优惠在一年中并非总有，大概只有黑色星期五和圣诞能有这种优惠）就有双核，虽然双核性能都是2.1GHz，并不高，但用于并行运行程序很合适，内存也很大(2G)，对香港的线路也比较好。
更新
VPS的配置和网速评测固然重要，VPS面板的好坏也直接影响用户体验，西蒙宫也整理了三款VPS面板方面的信息，参考VPS自带面板评测——搬瓦工、DigitalOcean、Virmach
友情提示
购买VPS请一定不要开代理，否则会被判欺诈，很麻烦的！
搬瓦工的评测看着我还是蛮心动的
感谢捧场！搬瓦工确实是一家有实力的提供商。
还是习惯便宜实惠的搬瓦工
