8步测评hardbirch的xen 512 Linux VPS

September 18th, 2012 Leave a comment Go to comments

很多同学在购买新的VPS以后,常常问yqf.me应该如何进行测试,来确定自己购买的VPS性能。yqf.me结合互联网上的相关文章,正好今天手里拿了一个Hardbirch xen 512 linux vps,顺便来个测评,总结如下:

•VPS的linux版本查看命令:cat /etc/issue
•VPS的资源消耗查看命令:top
•VPS的内存使用情况查看命令:free -m
•VPS的CPU信息查看命令:cat /proc/cpuinfo
•使用DD对VPS硬盘I/O进行读写性能测试
•VPS出口、入口网络性能测试
•使用UB软件对LinuxVPS性能综合跑分测试
•国内、国外以及VPS网站访问速度测试

一、VPS的linux版本查看

[[email protected] ~]# cat /etc/issue
CentOS release 5.8 (Final)
Kernel \r on an \m

二、VPS的资源消耗命令查看

top – 04:22:07 up 1 min,  1 user,  load average: 0.03, 0.01, 0.00
Tasks:  72 total,   1 running,  71 sleeping,   0 stopped,   0 zombie
Cpu(s):  0.0%us,  0.0%sy,  0.0%ni,100.0%id,  0.0%wa,  0.0%hi,  0.0%si,  0.0%st
Mem:    509592k total,    44816k used,   464776k free,     1872k buffers
Swap:   524280k total,        0k used,   524280k free,    22736k cached

以上可以查看服务器运行时间,负载情况,cpu占用情况,内存使用情况,等。

三、VPS的内存使用情况查看

[[email protected] ~]# free -m
total       used       free     shared    buffers     cached
Mem:           497         43        453          0          1         22
-/+ buffers/cache:         19        477
Swap:          511          0        511

四、VPS的CPU信息查看命令:cat /proc/cpuinfo

[[email protected] ~]# cat /etc/cpuinfo
cat: /etc/cpuinfo: No such file or directory
[[email protected] ~]# cat /proc/cpuinfo

附:CPU查询:www.anandtech.com/Benchwww.cpubenchmark.net
你可以在这个网站上,查到你使用VPS的CPU怎么样,综合评分如何等。然后,你要观察一下,一共给你几核,每核的频率是多少。总体来讲,单核高频不限,比多核低频的性能要好一些。以下是linode的cpu和hardbirch的VPS使用的cpu比较:

CPU Name Passmark CPU Mark Rank CPU Value Price
(higher is better) (lower is better) (higher is better) (USD)
Intel Xeon L5520 @ 2.27GHz 4901 163 7.54 $649.99**
Intel Xeon X3450 @ 2.67GHz 5223 149 19.49 $267.99*

五、硬盘IO性能测试

测试硬盘IO性能,对硬盘的损害很大,不建议多次或长时间尝试,命令如下:

dd if=/dev/zero of=test bs=64k count=4k oflag=dsync

测试结果,如果超过10M,对正常建站就无影响。超过50M,就是非常给力状态。

[[email protected] ~]# 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, 5.24762 s, 51.2 MB/s
[[email protected] ~]# dd if=/dev/zero of=test bs=64k count=8k oflag=dsync
8192+0 records in
8192+0 records out
536870912 bytes (537 MB) copied, 10.1032 s, 53.1 MB/s

六、网络性能测试

VPS的网络性能,主要分出口和入口二个指标,入口可以用wget文件得到:

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

看下载速度,如果是11M/s,大概就是百兆口。70M/S,大概就是G口。您的VPS搭建好网站环境后,可以用其它的VPS去拽这个文件,得到出口的带宽。

[[email protected] ~]# wget http://cachefly.cachefly.net/100mb.test
–2012-09-18 04:37:36–  http://cachefly.cachefly.net/100mb.test

2012-09-18 04:37:41 (19.9 MB/s) – `100mb.test’ saved [104857600/104857600]

七、UB跑分得到综合性能

一款国外提供的linux性能专用软件,可以跑出分数来让你做对比:

wget -c http://byte-unixbench.googlecode.com/files/UnixBench5.1.3.tgz

tar zxvf UnixBench5.1.3.tgz

cd UnixBench

make

./Run

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。

八、VPS的访问速度测试

这个主要测试是PING值,和观看TRACERT值,来判断速度。大概这几个网站:

站长站:ping.chinaz.com – ping.chinaz.com/tracert
卡卡网:www.webkaka.com/ping.aspxwww.webkaka.com/Tracert.aspx
国外的:www.just-ping.com 软件:speedtest.net/mini.php
国内的:www.17ce.com

综上,有测评结果来看,Hardbirch的xen 512 linux VPS还是对得起99元的价位的。
