限于时间原因，简单测评数据如下，
1）uptime
呵呵，至少我荒废这5天0宕机~
#uptime 11:59:31 up 5 days, 11:07, 1 user, load average: 0.00, 0.00, 0.00
2)宽带带宽测试
入口100Mbps
#wget http://cachefly.cachefly.net/100mb.test --12:06:53-- 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.

3）硬件配置
CPU给了4核E3-1270 v2（3.5GHz）算是很给力了。
