zenlayer陆续开了19个数据中心，本博客认为线路好的还是美国洛杉矶，双向cn2.比如日本的，我感觉一般般，如果一定需要日本独立机器，可以人工联系老易购买。下面简单对zenlayer的日本独立服务器进行测评：
2x Intel(R) Xeon(R) CPU E5-2620 v2 @ 2.10GHz
64GB RAM
4 x 600G SAS @ 10KRPM
RAID 0,1,5,10
1 IP Address
10Mbps (MAX:1Gbps)
1888RMB/月
额外带宽42元/1Mbps
1、ping.chinaz.com全国ping情况。通过ping看的话，机器虽然在日本，但是ping不是太理想，估计跟美国机器也差不多。
| 线路 | 最快节点 | 最慢节点 | 平均响应 |
| 电信 | 江苏泰州89ms | 北京238ms | 137.9ms |
| 多线 | 广东深圳118ms | 河南新乡242ms | 201.5ms |
| 联通 | 福建福州112ms | 广东深圳272ms | 204.4ms |
| 移动 | 江苏扬州131ms | 江苏常州281ms | 223.7m |
2、回程路由情况。zenlayer日本到广州电信，北京联通，北京移动路由情况参考下面。全部是走NTT。

3、去程路由情况，比如深圳电信到zenlayer日本路由情况，还是走NTT。
4、bench测试，可以看看cpu型号，内存大小，磁盘读写，已经带宽情况，zenlayer日本独立服务器默认带宽是10M。
5，亮点估计就是磁盘读写了。
# hdparm -Tt /dev/sda
/dev/sda:
Timing cached reads: 25254 MB in 2.00 seconds = 12646.25 MB/sec
Timing buffered disk reads: 2386 MB in 3.00 seconds = 794.67 MB/sec
