UnixBench是一个类unix系（Unix，BSD，Linux）统下的性能测试工具，一个开源工具，被广泛用与测试linux系统主机的性能
所谓跑分工具，不仅各项的测试有得分，最后跑完也会有一个综合的得分，这个分数是怎么来了？
其实，这个值是测试系统的测试结果与一个基线系统测试结果比较得到的指数值。
源于1995 年，基线系统是“George”，一个工作站：SPARCstation 20‐61，128MB RAM，Solaris2.3，此系统的指数值被设定为10，所以，如果一个系统的最后结果分数为520，意思是指此系统比基线系统运行快52 倍。
安装使用
Unixbench-5.1.2.tar.gz下载地址：http://soft.vpser.net/test/unixbench/
居然是2009年的版本，不得不说真是够老的
执行以下命令下载和安装：
cd /usr/local wget http://soft.vpser.net/test/unixbench/unixbench-5.1.2.tar.gz tar zxvf unixbench-5.1.2.tar.gz cd unixbench-5.1.2
如果不需要进行图形测试或者不在图形化界面下测试，则将Makefile文件中GRAPHIC_TESTS = defined注释掉（README文件中有说明）
然后make
make
如果make的时候报这个错：
这是因为上述图形测试的配置没有注释掉，而x11就是图形界面配置，处理：yum install xorg-x11* ，如果上述的GRAPHIC_TESTS = defined注释掉而忽略了图形测试，就不会报这个错
如上图，确定make成功，再Run
./Run
执行Run的时候如果报：Can't locate Time/HiRes.pm in @INC
处理：yum -y install perl-Time-HiRes
跑分结果
然后等待程序进行测试即可,这个过程可能比较漫长,请耐心等待，最后跑完将会有一个分数在底部出现，通常情况下1000分以上的VPS是性能较好的。

跑完会有两个分数结果，一个是 1 parallel process 的结果，另一个是4 parallel process 的结果 （如果是单核只会跑一次）。两者的区别即一个是单进程跑，一个是多进程跑 。
默认测试完成后测试结果会存放在results目录

额外说明
针对Pipe-based Context Switching测试项结果异常的问题，参考一篇博文：http://www.sohu.com/a/248896408_100113911
使用博文中提及的https://github.com/qcsuper/byte-unixbench的5.1.3版本
阿里云VM还是跑出了单项907.7的高分，gcp的VM只有166.7.....
