unixbench是linux下面常用的跑分软件,用于测试linux性能
下面是Centos7.6测试cpu性能
安装运行命令
安装编译环境
yum install make gcc gcc-c automake autoconf libtool gcc-c++ time perl-Time-HiRes SDL-devel mesa-libGL-devel -y 解压
tar xzf UnixBench5.1.3.tgz
(说明：unixbench5包含system和graphic测试，如果你需要测试graphic，则需要修改Makefile,不要注释掉"GRAPHIC_TESTS = defined，同时需要系统提供x11perf命令gl_glibs库。反之，请将Makefile文件中GRAPHICS_TEST = defined注释掉，然后编译运行。)
修改Makefile
cd UnixBench sed -i "s/GRAPHIC_TESTS = defined/#GRAPHIC_TESTS = defined/g" ./Makefile make安装
执行测试 ./Run (如果出现错误-bash: ./Run: /usr/bin/perl: bad interpreter: No such file or directory。输入yum groupinstall "Perl Support"即可)
使用方法：
执行system测试方法：Run
执行graphic测试方法：Run graphics
执行system,graphics测试方法：Run gindex
Run参数用法：
Run [ -q | -v ] [-i
选项说明：
-q 不显示测试过程
-v 显示测试过程
-i
-c
对于多cpu系统的性能测试策略，需要统计单任务,多任务及其并行的性能增强。
以4个cpu的PC为例，需要测试两次，4个CPU就是要并行执行4个copies，
例:Run -q -c 1 -c 4
