测试型号:基础 I 型 vCPU(1个)、内存(1G)、存储(80G)、IP(1个)、独享带宽2M — 价格:129元,更多型号参考:http://www.ctyun.cn/product/cloud
1. 系统版本
- [root@i-488-27138-VM ~]# cat /etc/issue
- CentOS release 6.3 (Final)
- Kernel \r on an \m
- [root@i-488-27138-VM ~]# uname -a

中国电信天翼云主机(貌似用的是Vmware)提供一些操作系统(Windows收费):
- Ubuntu 12.04 (64-bit)
- CentOS 5.8 (64-bit)
- CentOS 6.3 (64-bit)
- CentOS 6.4 (32-bit)
- Debian 7 (64-bit)
Windows除了基础 I 型,其他型号Windows都要收费,大家还是用Linux吧,哈哈!

7. 用unixbench测试VPS性能(详细步骤)
取得root权限,然后随便找个目录,比如可以cd ~或者cd /tmp
- yum -y install gcc
- wget http://byte-unixbench.googlecode.com/files/unixbench-5.1.2.tar.gz
- tar -zxvf unixbench-5.1.2.tar.gz
- cd unixbench-5.1.2
- vi Makefile 找到GRAPHIC_TESTS = defined,在前面加个“#”,然后保存退出
- make
- ./Run
Benchmarks报告如下:

总结
可能是刚刚开放测试,后台功能不全,bug多(重装系统后,密码登陆进不去,提示密码错误,重置很多次后才成功),重装次数限制8小时/次。价格没有优势。中国特色网络(无语),对联通、教育网来说有点慢,2M带宽平均500k左右,dd磁盘速度50+M/s,还算可以,比aliyun好多了(ps:aliyun测试25M/s),从Benchmarks得分来看1000+,分数不错。
