digitalocean

DigitalOcean是一家美国公司开办的VPS服务商,本站介绍过一次,之前是只有纽约机房,对国人来说速度没办法接受。现在最新上线美国旧金山机房,国内速度非常快。512M KVM VPS给到20G的SSD硬盘,并且只需5美元,性价比超高了。入手了这款VPS,给大家分享下这款VPS的一些测试数据,仅供大家参考。

1、安装lnmp只花了17分钟,以下是安装lnmp后的内存情况。

[root@digitalocean ~]# free -m
             total       used       free     shared    buffers     cached
Mem:           502         55        447          0          0         17
-/+ buffers/cache:         37        464
Swap:            0          0          0

2、网络带宽测试:(速度很给力,G口的带宽)

命令:wget http://cachefly.cachefly.net/100mb.test

[root@digitalocean ~]# wget http://cachefly.cachefly.net/100mb.test
--2013-05-14 11:44:57--  http://cachefly.cachefly.net/100mb.test

Saving to: `100mb.test.1'

100%[======================================>] 104,857,600 22.1M/s   in 4.6s

3、硬盘IO测试:(SSD硬盘IO要明显好很多)

因为是SSD硬盘,我们测试方法和普通硬盘不一样, 命令:hdparm -t /dev/xvda(硬盘设备, 也可能是/dev/sda或则/dev/sda1等,可以通过命令fdisk -l查看。)可以执行yum install hdparm安装。DigitalOcean的结果如下:

[root@digitalocean ~]# hdparm -t /dev/hda

/dev/hda:
 Timing buffered disk reads:  986 MB in  3.00 seconds = 328.15 MB/sec

4、CPU信息:(CPU是1核心的,因为是KVM,所有获取不到CPU信息,参考意义不大)

命令:cat /proc/cpuinfo

[root@digitalocean ~]# cat /proc/cpuinfo
processor : 0
vendor_id : GenuineIntel
cpu family : 6
model : 2
model name : QEMU Virtual CPU version 1.2.0
stepping : 3
cpu MHz : 2299.998
cache size : 4096 KB
fdiv_bug : no
hlt_bug : no
f00f_bug : no
coma_bug : no
fpu : yes
fpu_exception : yes
cpuid level : 4
wp : yes
flags : fpu de pse tsc msr pae mce cx8 apic mtrr pge mca cmov pat pse3
6 clflush mmx fxsr sse sse2 syscall nx lm up pni vmx cx16 popcnt lahf_lm
bogomips : 4599.99

5、unixbench综合测试:(非常不错的分数:1040.9)
总分情况,低于400的就算性能低下;600-800是属于正常VPS水准;超过1000分性能就算给力。
命令:wget http://www.CTOHome.com/linux-vps-pack/unixbench.sh;sh ./unixbench.sh;
