求VPS美國KT之前的云主機是vmware虛擬技術，今天上線了一個KVM虛擬技術的云主機，目前開通的有洛杉磯機房，可以去易秋網絡官網下單，后面估計會陸續開通新加坡機房/香港機房。今天先簡單測評一下KT美國KVM虛擬技術的云主機。再說點題外話，其實KT的kvm要比同時代的linode/日本櫻花VPS落后了有個2-5年時間。
1、ping.chinaz.com情況.
| 線路 | 最快節點 | 最慢節點 | 平均響應 |
| 電信 | 廣東佛山164ms | 四川成都293ms | 212.8ms |
| 多線 | 江蘇常州164ms | 江蘇南京482ms | 212.8ms |
| 聯通 | 廣東深圳155ms | 黑龍江哈爾濱258ms | 196.9ms |
| 移動 | 廣東深圳155ms | 河南新鄉232ms | 186.3ms |
2、回程路由，可以看看KT美國到廣東電信，北京聯通，北京移動路由情況。電信走cn2.

3、去程路由情況，比如深圳到美國KT路由，也是cn2.
4、superbench測試。可以看看cpu型號，磁盤讀寫，以及帶寬情況。
