vultr日本数据中心评测-啊福主机

Vultr这货是digitalocean最有力的竞争者和替代品，其多数据中心和更高的配置很快就赢得了用户的青睐。好吧，这可能是阿福的一厢情愿。等阿福了解了其性能之后再做评论把。

评测配置：

CPU：1核心

内存：768M

硬盘：15G

流量：200G（这个较之前的100G有所提升）

IPs：1IPv4

架构：KVM（可自行上传ISO嗯，自备网卡驱动）

可选系统：Linux

套餐：最低配置

测试项目一：

CPU信息：

CPU核心数量的多少代表着你多线程运行的程序的快慢。当然性能不是绝对有优势的，看卖家把U平分到多少个人头上。不过一般来说U核心越多，性能越好。

[root@vultr ~]# cat /proc/cpuinfo
processor   : 0
vendor_id   : GenuineIntel
cpu family   : 6
model       : 60
model name   : Vultr Virtual CPU 2
stepping   : 1
cpu MHz       : 3600.010
cache size   : 4096 KB
physical id   : 0
siblings   : 1
core id       : 0
cpu cores   : 1
apicid       : 0
fdiv_bug   : no
hlt_bug       : no
f00f_bug   : no
coma_bug   : no
fpu       : yes
fpu_exception   : yes
cpuid level   : 13
wp       : yes
flags       : fpu de pse tsc msr pae mce cx8 apic mtrr pge mca cmov pat pse36 clflush mmx fxsr sse sse2 ht syscall nx rdtscp lm constant_tsc up pni ssse3 cx16 sse4_1 sse4_2 popcnt lahf_lm
bogomips   : 7200.02

从CPU的频率不难看出是E3的U（好吧，如有更老的高频U，各位赶紧指正，阿福不胜感激！）

测试项目二：

空载内存信息：

内存是一个VPS最重要的部分之一。显然内存越大能够运行的程序越多，能够承载的访问量也越多。

[root@vultr ~]# free -m
total       used       free     shared    buffers     cached
Mem:           756         81        674          0          5         35
-/+ buffers/cache:         40        716
Swap:            0          0          0

空载实际使用内存40M！显然优化的很成功！

硬盘：

[root@vultr ~]# df -h
Filesystem            Size Used Avail Use% Mounted on
/dev/vda1              15G 1.8G   13G 13% /
tmpfs                 379M     0 379M   0% /dev/shm

CentOS 5该有的都有了。1.5G算是完整版的server系统

测试项目三：

硬盘IO测试：

DD测试硬盘

[root@vultr ~]# dd if=/dev/zero of=test bs=128k count=4k oflag=dsync
4096+0 records in
4096+0 records out
536870912 bytes (537 MB) copied, 4.93631 seconds, 109 MB/s
[root@vultr ~]# dd if=/dev/zero of=test bs=128k count=4k oflag=dsync
4096+0 records in
4096+0 records out
536870912 bytes (537 MB) copied, 5.26191 seconds, 102 MB/s
[root@vultr ~]# dd if=/dev/zero of=test bs=128k count=4k oflag=dsync
4096+0 records in
4096+0 records out
536870912 bytes (537 MB) copied, 4.85201 seconds, 111 MB/s

hdparm专用测试软件测试硬盘。

[root@vultr dev]# hdparm -t /dev/vda

/dev/vda:
Timing buffered disk reads: 1032 MB in 3.00 seconds = 343.47 MB/sec
HDIO_DRIVE_CMD(null) (wait for flush complete) failed: Inappropriate ioctl for device
[root@vultr dev]# hdparm -t /dev/vda

/dev/vda:
Timing buffered disk reads: 1042 MB in 3.00 seconds = 346.90 MB/sec
HDIO_DRIVE_CMD(null) (wait for flush complete) failed: Inappropriate ioctl for device
[root@vultr dev]# hdparm -t /dev/vda

/dev/vda:
Timing buffered disk reads: 1044 MB in 3.00 seconds = 347.89 MB/sec
HDIO_DRIVE_CMD(null) (wait for flush complete) failed: Inappropriate ioctl for device

IO很稳定，比一般的HDD的raid10还要OK，当然SSD不是盖的（PS，一般SSD能有400-500M/S的读和写，写可能会低点，显然他们把SSD的性能用到了极限，但还保留一定的性能做突发）

测试项目四：

端口速率：

Port Speed

IN速率：

[root@vultr dev]# wget http://cachefly.cachefly.net/100mb.test

G口的进口，速度非常不错

OUT 速率测试

采用linode廉价10美元产品测试

wget -c http://104.156.226.151/100mb.test

2014-10-02 07:00:41 (4.45 MB/s) – `100mb.test’ saved [104857600/104857600]

可以看到速率还是不错的，4M/S的平均速率，不过到国内可能就要大打折扣了。
