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数据中心,25G硬盘，500G流量，一个IPV4，首月付款2.99美元，次月续费8.99美元，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的评测数据：
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？ root@vps:/# dd if=/dev/zero of=test bs=64k count=4k oflag=dsync 4096+0 records in 4096+0 records out 268435456 bytes (268 MB) copied, 4.5251 s, 59.3 MB/s
网络下载测速，100M端口没什么好说的了。 root@vps:/# wget http://cachefly.cachefly.net/100mb.test --2012-12-01 22:16:33-- http://cachefly.cachefly.net/100mb.test Resolving cachefly.cachefly.net... 205.234.175.175 Connecting to cachefly.cachefly.net|205.234.175.175|:80... connected.
