猛然间产生一种念想，微魔部落虽然被冠上了“VPS测评站”的名号，但是距离上次发布相关测评已经具有相当的时间了，感觉十分对不起观众。正好最近入手了一个RamNode的年付128M内存的OVZ（凭借优惠码：LET30，促销优惠价：年付16.8美元），整体感觉价格还是不错的。今天就顺带着给大家一起拿出来鉴赏吧。
RAMNode – 16.8美元年付 128M 20G OVZ 亚特兰大 简单评测

虽然，在上面的结果中已经包含了CPU的信息，但是这里还是多此一举的看看CPUinfo吧~采用命令：
cat /proc/cpuinfo

硬盘测试
命令行：
dd if=/dev/zero of=test bs=64k count=4k oflag=dsync
受益于SSD的缓存，硬盘的DD结果也十分理想。输出结果：

UnixBench跑分
apt-get install gcc libxext-dev libgl1-mesa-dev wget http://byte-unixbench.googlecode.com/files/unixbench-5.1.2.tar.gz tar -zxvf unixbench-5.1.2.tar.gz cd unixbench-5.1.2 make ./Run
运行UnixBench，得分也很不错~

4.测试总结
通过一些列测评，给微魔留下最深刻的影响的是硬盘，毕竟有SSD缓冲，效果不错，同时默认支持ipv6（16个），且在订购之后就会默认分配好，算是比较贴心的~。但在使用中也遇到了一些问题。微魔默认安装了主机商提供的Debian 6 32 bit Minimal的系统模版，但是默认的更新源是德国的镜像，因此在安装更新（运行apt-get upgrade）的时候非常的痛苦，虽然大家可以通过vi /etc/apt/sources.list来完成修改，但微魔觉得事先的优化还是应该先做好。
可以开通VPN么?
一般都可以，详情可以咨询主机商~
挂完站没？打开速度如何啊？ 亚特兰大啊，不知道线路如何？走什么线路？
还没挂站，一直闲置着呢~速度和线路看官方给的测试ip吧
我买的512m openvz的,硬盘测试读写200m/s
