maximumvps-64m内存KVM简单测评

主机测评上才发布maximumvps的文章不久（maximumvps-kvm全面上货,最低8.5美元年付）我这里就自己买了个想做个测评发给大家看看，如实从节约的理念出发买了个64M内存的最便宜的。洛杉矶数据中心，系统里面里面有ISO和net-install版本的debian、centos等，但是没有我喜欢的minimal，全面的评价一下就是这价格还是可以了，建站没啥问题的，慢慢开始折腾吧：

内存情况：（等会让自己加点swap）

看看CPU，其实官方公布了为Dual L5420

安装好系统后就这情况：
root@debian:~# df -lh

下载测试一把速度：

DD测试，后面有90多M

跑个比较全面的脚本：
