vpsunlimited 512M内存（xen）VPS简单测评
晚上八点左右下单买了vpsunlimited.com的这款512内存的VPS，是基于XEN，location是los angeles的QR机房,25G硬盘，500G流量，一个IPV4，首月付款2.99刀，次月续费8.99刀，基于这一点我就先买了一个试试，如果还行我就下个月再继续续费。下面上张环境编译完成后的图：
下面给出简单的vpsunlimited.com家这款512M内存的VPS的测评数据：
先看硬盘I/O，个人觉得还凑合，主要是晚上十点测试的也算是老外的高峰期了吧？

网络下载测速，100M端口没什么好说的了。

然后看看CPU，说的是4核，看了下CPU没有限制频率，这样好坏处都有；
