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
| 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 |

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。
| 序号 | Ping的地点 | 响应IP | 响应时间 | TTL |
|---|---|---|---|---|
| 1 | 襄阳[电信] | 111.123.x.x | 58毫秒 | 121 |
| 2 | 南宁[电信] | 111.123.x.x | 33毫秒 | 119 |
| 3 | 厦门[电信] | 111.123.x.x | 39毫秒 | 120 |
| 4 | 上海[移动] | 111.123.x.x | 171毫秒 | 117 |
| 5 | 浙江[移动] | 111.123.x.x | 178毫秒 | 115 |
| 6 | 山东[联通] | 111.123.x.x | 157毫秒 | 116 |

| 11 | 合肥[电信] | 111.123.x.x | 55毫秒 | 119 |
| 12 | 乐山[电信] | 111.123.x.x | 29毫秒 | 121 |
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 --2011-09-11 15:39:51-- 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.

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：
- 稳定性有待考验~
优点：
- 国内VPS，速度不错，Win下的远程桌面也很顺畅~
- 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~
This was so helpful and easy! Do you have any atrilces on rehab?
建议更新下吧，贵州早就悲剧了
呵呵，谢谢提醒~更新！
