标题：【警惕】Contabo的IO只能看看，严重不推荐购买Contabo的存储型

摘要：Contabo的高明之处：

Contabo的IO只有在跑分脚本测试的时候看的还不错，
实际用起来，那IO应该限制的非常低，甚至都不如石头盘

实测
contabo打包120G文件（非小文件，都是几M几十M几百M的文件），用了17小时以上
而同样的文件在psychz的5刀D525上打包，只需要3个小时左右
猜测：contabo可能像T5突发实例一样对持续IO限制的非常低，但是测试IO的时候突发IO看起来很好看。

可以看看下面的curl -sL yabs.sh | bash的跑分对比，
很好看的，比psychz的IO好看的多，是psychz的IO的4倍，但也就是很好看而已
