1.unixbench 是什么?
unixbench 是一套 unix 系统基准测试套件。unixbench 的设计目标是为类 unix 系统提供一套基本的指标，所以有许多项目测试系统各方面的性能。各项的测试有得分，然后有一个综合的得分，这样可以很方便的通过分数去比较。
unixbench 也包含一些非常简单的 2D 和 3D 图形测试。
unixbench 也支持多 CPU 系统的测试，默认的行为是测试两次，第一次是一个进程的测试，第二次是 N 份测试，N 等于 CPU 个数。这样的设计是为了以下目标：
1)测试系统的单任务性能
2) 测试系统的多任务性能
3) 测试系统并行处理的能力
unixbench 一个基于系统的基准测试工具，不单纯是 CPU 内存 或者磁盘测试工具。测试结果不仅仅取决于硬件，也取决于系统、开发库、甚至是编译器。
2. 安装依赖包
yum -y install perl perl-Time-HiRes
3. 注释掉 Makefile 中如下(如不测试图形)
#GRAPHIC_TESTS = defined
4. 执行 unixbench
[root@Oracle unixbench-5.1.2]# ./Run
make all
make[1]: Entering directory `/root/unixbench-5.1.2′
Checking distribution of files
./pgms exists
./src exists
