在11月2日从alienVPS购买了虚拟主机，对于其表现不是很了解，多数信息都是来自于网上的推荐，所以决定选择了其中最便宜的UF1方案试用。方案提供25GB硬盘空间、每月250GB的流量、256MB独享内存，价格是$5/month，如果季付还可以优惠到$13.95。从价格上来讲，算是vps中比较便宜的了 ，而且又能提供如此的配置，性价比算是比较高的。

到现在使用已满30天，在这一个月的使用当中，总体感觉很一般，有3点比较失望。第一，alienVPS开通时间比较慢，从paypal付费完成，到vps上线一共花费大约20小时。第二，从北方联通的网络访问速度比较慢，ping值一般在400ms左右，300ms以下的时候也有，但是不多。从电信网络访问稍快，ping值在300ms左右，比网通稍好。我原本期望值能够在200ms左右，但很不幸。第三就是uptime实在非常失望，其中有2次vps宕机。一次是在vps莫名其妙的挂掉，进入CP后reboot就好了；另外一次更夸张，居然连CP都进不去，后来从static中看到停止响应的时间超过了12小时。在宕机期间，alienvps的网站后台也没有任何声明或公告……

最后是unixbench的测试方法和结果。从www.tux.org下载 unixbench-4.1.0.tgz，解压缩后进入目录，直接./Run开始运行

# wget http://www.tux.org/pub/tux/niemi/unixbench/unixbench-4.1.0.tgz
# tar zxf unixbench-4.1.0.tgz
# cd unixbench-4.1.0
