你应该选择哪个vps主机：Linode, amazon EC2，阿里云，盛大云性能测试报告征集中

其实选择哪个VPS我们会经常在讨论的是ping值是多少，但是vps还有很多非常重要的指标。这些指标可以让你知道vps系统的性能。而且我也很好奇，国内的云主机性能到了什么样的程度。我打算开始征集Linode，amazon EC2，阿里云，盛大云性能测试报告。当然，你如果用其他的vps，也可以贴上来。

测试方法：使用byte-unixbench进行测试：byte-unixbench是专门用来测试unix系统性能的benchmark。
你可以在这儿下载一份：
http://code.google.com/p/byte-unixbench/

参照readme文件指令进行测试，非常简单，不需要花很长的时间。但是要保证你的系统中没有运行其它的程序，最好是只有操作系统进行测试。当然测试结果会跟你的内存，cpu有关系，所以我建议的baseline是 *512M ram, 4cpu*。

测试完成之后会生成这样的报告，你们可以贴上来，看看这些主机之间的差距有多少，会给你选择主机很大的帮助：
