RamNode一直有着不错的口碑,并且在LEB上排名前三。昨天有分享他们的最新优惠码,趁着这个机会,入手了这款256M KVM VPS,我选择的是西雅图机房带SSD硬盘这款。分享这款VPS的一些测评数据,仅贡大家参考。首先看下配置:

  • 内存:256M
  • 硬盘:5G SSD硬盘
  • 流量:100G/月
  • CPU核心:1核
  • 独立ip:1个
  • KVM/SolusVM

1、安装lnmp花了30分钟左右,以下是安装lnmp后的内存情况。

[root@ramnode ~]# free -m
             total       used       free     shared    buffers     cached
Mem:           249        113        135          0          4         44
-/+ buffers/cache:         64        184
Swap:            2          0          2

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@ramnode ~]# wget http://cachefly.cachefly.net/100mb.test
--2013-07-20 10:37:35--  http://cachefly.cachefly.net/100mb.test

Saving to: `100mb.test'

100%[======================================>] 104,857,600 64.1M/s   in 1.6s

3、硬盘IO测试()

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/vda1(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。RamNode的结果如下:

[root@ramnode ~]# hdparm -t /dev/vda1

/dev/vda1:
 Timing buffered disk reads:  860 MB in  3.00 seconds = 286.60 MB/sec

4、CPU信息:(CPU是1核心的,因为是KVM VPS,看不到使用哪款CPU,从购买页面看应该是E5)

[root@ramnode ~]# cat /proc/cpuinfo
processor : 0
vendor_id : GenuineIntel
cpu family : 6
model : 13
model name : QEMU Virtual CPU version (cpu64-rhel6)
stepping : 3
cpu MHz : 3400.022
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 cx16 lahf_lm
bogomips : 6800.04

5、unixbench综合测试:(性能不错,超1000分了。)
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;
