EMSVPS 512M 国内免备Xen Linux VPS简单评测

EMSVPS不想多介绍了,最近几天的文章都是关于这家的。微魔上次给大家简单测试了这家最新推出的84元/月国内免备VPS,文章是在Windows下进行的(点击查看)。大家普遍反映Win下的测试看起来不太直观。呵呵,其实我自己对Win下的测评也不是很懂,所以这里再给大家专门写一篇Linux下的测评吧。另外,顺便说,这款测试用VPS目前闲置,有兴趣接手的童鞋不妨和我联系,续费84元(原价120元)。测试开始!

Update:2011/10/1:EMSVPS因为一些原因,目前已经放弃国内VPS的计划!

EMSVPS 512M 国内免备Xen Linux VPS简单评测

本次测试系CentOS 5.6 32位系统下进行

测试内容:

  1. 产品配置及测试环境
  2. 网络测试
  3. 硬件测试
  4. 测试总结

1.产品配置及测试环境

CPUs 2
独立内存 512MB
磁盘空间 30GB
Raid 10 Yes
带宽 2000GB
端口速度 100M bps
IPv4 1
控制面板 SolusVM
技术支持 No
操作系统 Linux/Windows
价格 84元/月(原价120元)

2.网络测试

Ping值测试

呵呵,其实不用多说也知道,国内的VPS ping值优势自然明显。

wget测速

命令行:

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

宽带可达50M,结果如下,

[root@MyVPS ~]# wget http://cachefly.cachefly.net/100mb.test

至于单线程的下载测速,由于大家的网络环境各不相同,而更关键的是我目前的网络环境是校园网,呵呵,所以我的单线程下载速度(20KB/s左右)更是只能“仅作参考”了~

3.硬件测试

硬件概况

采用命令行:

wget http://aspersa.googlecode.com/svn/trunk/summary
chmod a+x summary
./summary

CPU:i5-2310 CPU @ 2.90GHz,其他输出结果如下:

硬盘测试

命令行:

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

硬盘还可以,不是石头~输出结果:

UnixBench跑分

运行UnixBench(需安装make gcc)得分还算不错~

4.测试总结

言简意赅地总结一下~

缺点:

  1. 稳定性有待考验~

优点:

  1. 国内VPS,速度不错,Win下的远程桌面也很顺畅~
  2. 免备,呵呵,不解释咯~

最后,本VPS目前测试完毕,已经闲置,请有兴趣接手的童鞋与我QQ联系:464592664,注明“EMSVPS”,价格再议~
