Vultr Dedicated Cloud日本独立云主机简单测评

VDC,Vultr Dedicated Cloud,简称VDC(俗称大号KVM),与VULTR普通SSD云服务器的最大区别是资源独占,也就是说VDC的资源都是独占的,不和其它邻居共用资源,包括最重要的内存和CPU。众所周知,日本机房到国内的网速很快,并且很稳定,带宽比国内的便宜多了,端口速率也非常快,每个VDC都有1Gbps的端口速率。VDC可以在1分钟内完成部署,是传统独立服务器上架时间无法相比的。

老易开始还以为是独立服务器,其实不是,下面附带简单测评一下。

1、系统老易选的centos 6 64bit,后台可以自定义ISO的。KVM虚拟技术,可以传ISO安装windows.

[root@test ~]# cat /etc/issue
CentOS release 6.8 (Final)
Kernel \r on an \m

[root@test ~]# uname -a
Linux test.yqf.me 2.6.32-642.6.2.el6.x86_64 #1 SMP Wed Oct 26 06:52:09 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux

2、磁盘120G SSD,给力。

[root@test ~]# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/vda1 109G 892M 102G 1% /
tmpfs 3.9G 0 3.9G 0% /dev/shm

3、磁盘读写,就SSD而言,还算凑合。

[root@test ~]# 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, 2.95852 s, 90.7 MB/s
[root@test ~]# 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, 3.4955 s, 307 MB/s

4、内存给了8G。

[root@test ~]# free -m
total used free shared buffers cached
Mem: 7872 157 7714 0 7 49
-/+ buffers/cache: 100 7771
Swap: 0 0 0

5、CPU,型号是虚拟型号,不敢露脸,这个不厚道。

6、带宽测试,入口带宽。下载日本的ISO,100M满速。

7、路由跟踪了下,NTT线路。
