实测美国KT云主机走电信cn2

去年老易对美国KT云主机G1-1套餐做了简单测评,可以回头看看KT美国云主机G1-1套餐简单测评,当时测的KT美国云主机,走的是PCCW。后来我问美国方面,美国方面说KT所有的云主机走的是CN2,再后来我有时候下单买机器,有时候是显示电信骨干网,不走cn2。所以我也不能打包票说,KT美国云主机,一定走电信CN2。到底走不走cn2,要看运气了。今天给客户下单一个KT美国云主机,走的是CN2,附带简单测评。

1、系统客户要的centos 6 64bit

[root@laoyi20160804a ~]# cat /etc/issue
CentOS release 6.5 (Final)
Kernel \r on an \m

[root@laoyi20160804a ~]# uname -a
Linux laoyi20160804a 2.6.32-431.el6.x86_64 #1 SMP Fri Nov 22 03:15:09 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux

2、内存1G。

[root@laoyi20160804a ~]# free -m
total used free shared buffers cached
Mem: 996 122 873 0 12 44
-/+ buffers/cache: 65 930
Swap: 2015 0 2015

3、CPU,超值。Intel(R) Xeon(R) CPU E5645 @ 2.40GHz比较常见。

[root@laoyi20160804a ~]# cat /proc/cpuinfo
processor : 0
vendor_id : GenuineIntel
cpu family : 6
model : 37
model name : Intel(R) Xeon(R) CPU E5645 @ 2.40GHz

4、磁盘40G。比之前的20G是扩大了一倍。

[root@laoyi20160804a ~]# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/mapper/VolGroup-lv_root 37G 2.4G 33G 7% /
tmpfs 499M 0 499M 0% /dev/shm
/dev/sda1 485M 34M 426M 8% /boot

5、磁盘读写,非常棒,难道是用的人少,磁盘读写好?

[root@laoyi20160804a ~]# dd if=/dev/zero of=test4 bs=64k count=4k oflag=dsync
4096+0 records in
4096+0 records out
268435456 bytes (268 MB) copied, 5.1457 s, 52.2 MB/s
[root@laoyi20160804a ~]# dd if=/dev/zero of=test2 bs=64k count=16k conv=fdatasync
16384+0 records in
16384+0 records out
1073741824 bytes (1.1 GB) copied, 2.41768 s, 444 MB/s

6、跟踪路由,来回都是cn2。

12 * * *

7、简单Ping测试。老易ping了下,非常稳定,就美国机器来说,是相当好的,稳定在160ms左右。
