KVMLA是一家国人开办的vps主售美国vps,最新上线凤凰城IOF机房,给到2款特价VPS,512M Xen VPS只需49元,1G Xen VPS只需98元。手上拿到1G这款,分享下这款VPS的一些测试数据,仅供大家参考,总体来看性能非常给力,值得购买。
1、安装lnmp只花了19分钟,以下是安装lnmp后的内存情况。
[root@kvmla ~]# free -m
total used free shared buffers cached
Mem: 1024 111 912 0 3 41
-/+ buffers/cache: 66 957
Swap: 511 0 511
2、网络带宽测试:(速度很不错,G口的带宽)
命令:wget http://cachefly.cachefly.net/100mb.test
[root@kvmla ~]# wget http://cachefly.cachefly.net/100mb.test
--2013-05-27 18:15:36-- http://cachefly.cachefly.net/100mb.test

3、硬盘IO测试(测试3次,结果都很给力。)
命令:dd if=/dev/zero of=test bs=64k count=4k oflag=dsync
[root@kvmla ~]# dd if=/dev/zero of=test bs=64k count=4k oflag=dsync

4、CPU信息(这款1G内存给到了4核心,cpu是E3-1240)
命令:cat /proc/cpuinfo
[root@kvmla ~]# cat /proc/cpuinfo

5、unixbench综合测试:(分数高达1261.5)
总分情况,低于400的就算性能低下;600-800是属于正常VPS水准;超过1000分性能就算给力。
命令:wget http://www.CTOHome.com/linux-vps-pack/unixbench.sh;sh ./unixbench.sh;
