DigitalOcean超值5美金ssd磁盘的VPS,赶超linode

digitalocean.ssd

DigitalOcean官方网站,人们常说的DO,今天刚好有空,顺便注册了一个,体验下,感觉还不错,5美金的VPS,还是SSD,不是很好找。我选的是最基础的VPS套餐:512M内存,单核,20GSSd,1TB流量,旧金山机房,跑个博客按说够用了。根据我接下来安装lnmp一键包的体验来看,只需20分钟即可编译安装lnmp环境,实际上,性价比肯定超过linode了。

1、我选的是centos 6 32bit.

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

[[email protected] ~]# uname -a
Linux my.v2kt.com 2.6.32-431.1.2.0.1.el6.i686 #1 SMP Fri Dec 13 11:45:23 UTC 2013 i686 i686 i386 GNU/Linux

2、CPU,单核,不显示型号。

[[email protected] ~]# cat /proc/cpuinfo

cpu family : 6

model name : QEMU Virtual CPU version 1.0

bogomips : 4599.99
clflush size : 64
cache_alignment : 64
address sizes : 40 bits physical, 48 bits virtual
power management:

3、内存512M。

[[email protected] ~]# free -m
total used free shared buffers cached
Mem: 498 51 447 0 4 27
-/+ buffers/cache: 19 479
Swap: 0 0 0

4、磁盘20G。

[[email protected] ~]# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/vda 20G 849M 18G 5% /
tmpfs 250M 0 250M 0% /dev/shm

5、DD测试下磁盘性能,估计他家低端的VPS套餐超售了,没有别家的SSD磁盘DD测试数据高,不过也不错了。

dd if=/dev/zero of=test bs=64k count=4k oflag=dsync
4096+0 records in
4096+0 records out
268435456 bytes (268 MB) copied, 6.25624 s, 42.9 MB/s

[[email protected] ~]# dd if=/dev/zero of=test bs=64k count=16k conv=fdatasync
16384+0 records in
16384+0 records out
1073741824 bytes (1.1 GB) copied, 2.18878 s, 491 MB/s

6、入口带宽测试,至少是100Mbps,因为我下载日本VPS的iso(日本出口是100Mbps)满速。

100%[======================================>] 687,075,328 11.3M/s in 60s

2013-12-28 22:40:25 (10.8 MB/s) – “win2003.32.virtio.isoâ€

7、出口带宽测试。

具体数据就不提供了,群里网友测试,出口带宽有100Mbps.

8、UnixBench跑分测试,单核,也不错了,900多分。
