digitalocean kvm vps简单测评(512M旧金山)

刚买的digitalocean的VPS，基于KVM，选的是旧金山数据中心对国内非常友好电信和联通都是直连的。简单的查看了一下VPS的参数，CPU被虚拟了，限制2G主频对于建站来说足够了，wget下载看来G口无疑了，后台有一键备份工具非常简单，如果数据丢失可以一键还原。官方网站：www.digitalocean.com 贴上来，后面再去折腾吧：

据我所知，国人对于ping非常的看重（下图是主机测评购买的旧金山VPS ping测试）：

下载 这块儿我们都很重视，检测带宽的标准，差不多G口吧：看看本人6M广州联通下载测试：

CPU的情况，基于KVM坑定是被虚拟过的，不过还给了2299Mhz的主频我想建站绰绰有余！
