求VPS美国KT之前的云主机是vmware虚拟技术，今天上线了一个KVM虚拟技术的云主机，目前开通的有洛杉矶机房，可以去易秋网络官网下单，后面估计会陆续开通新加坡机房/香港机房。今天先简单测评一下KT美国KVM虚拟技术的云主机。再说点题外话，其实KT的kvm要比同时代的linode/日本樱花VPS落后了有个2-5年时间。
1、ping.chinaz.com情况.
| 线路 | 最快节点 | 最慢节点 | 平均响应 |
| 电信 | 广东佛山164ms | 四川成都293ms | 212.8ms |
| 多线 | 江苏常州164ms | 江苏南京482ms | 212.8ms |
| 联通 | 广东深圳155ms | 黑龙江哈尔滨258ms | 196.9ms |
| 移动 | 广东深圳155ms | 河南新乡232ms | 186.3ms |
2、回程路由，可以看看KT美国到广东电信，北京联通，北京移动路由情况。电信走cn2.

3、去程路由情况，比如深圳到美国KT路由，也是cn2.
4、superbench测试。可以看看cpu型号，磁盘读写，以及带宽情况。
