digitalocean-2g内存/旧金山/简单测评

digitalocean在目前来说性价比应该也是数一数二了的，当然这只是我个人的观点不一定对！之前写过digitalocean的那款512M内存的检测测评，这里想看看在CPU加了1核而且内存扩大的情况下会不会有些变化，有兴趣的可以在本帖反馈下你们的结果，说说情况如何？！官方网站：www.digitalocean.com 具体大家看看下面的这些数据吧：

基本信息:基于KVM，2G内存，40G SSD硬盘，2核【cpu MHz : 2299.998】，美国西海岸的 旧金山数据中心,操作系统为debian7[64]，无swap【可自行修改，本帖测试默认无】！

都说是G口，第一次测试有点小遗憾：

拖日本的数据能有这样该知足了：
