serversanddomains

ServersAndDomains老牌美国服务商,最近别人介绍才知道有这么一家VPS商。优势是有自己的机房,并且VPS是有点云VPS的感觉,可以自己选择内存、CPU和硬盘等,并且有windows系统可以选择。这里我们选择最低配置1G Xen VPS,价格是月付9美元,机房是在洛杉矶,国内访问速度不错,以下是这款VPS的简单测试数据,仅供大家参考。

1、安装lnmp竟然花了1个半小时,比较蛋疼,以下是安装lnmp后的内存情况。

[root@ssd ~]# free -m
             total       used       free     shared    buffers     cached
Mem:          1024        385        638          0          0        354
-/+ buffers/cache:         31        992
Swap:            0          0          0

2、网络带宽测试:(速度很给力,G口的带宽)

命令:wget http://cachefly.cachefly.net/100mb.test

[root@ssd ~]# wget http://cachefly.cachefly.net/100mb.test
--2013-05-13 22:42:43-- http://cachefly.cachefly.net/100mb.test

100%[======================================>] 104,857,600 18.3M/s in 5.3s

3、硬盘IO测试(没什么亮点,比较普通)

命令:dd if=/dev/zero of=test bs=64k count=4k oflag=dsync

[root@ssd ~]# 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, 19.7217 seconds, 13.6 MB/s

4、CPU信息(我自己的是不喜欢E5这样的大母鸡,最多能接受E3了。)

命令:cat /proc/cpuinfo

[root@ssd ~]# cat /proc/cpuinfo

vendor_id : GenuineIntel

5、unixbench综合测试:(比较悲催的是分数只有382.4

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;

6、测试速度,给到chinaz Ping检测的结果。(速度还是不错的)
