UnixBench测试
测试项目:
Dhrystone测试
测试聚焦在字符串处理，没有浮点运算操作。这个测试用于测试链接器编译、代码优化、内存缓存、等待状态、整数数据类型等，硬件和软件设计都会非常大的影响测试结果。
Whetstone 测试
这项测试项目用于测试浮点运算效率和速度。这项测试项目包含若干个科学计算的典型性能模块，包含大量的C语言函数,sin cos sqrt exp和日志以及使用整数和浮点的数学操作。包含数组访问、条件分支和过程调用。
Execl Throughput（execl 吞吐，这里的execl是类unix系统非常重要的函数，非办公软件的execl）测试
这项测试测试每秒execl函数调用次数。execl是 exec函数家族的一部分，使用新的图形处理代替当前的图形处理。有许多命令和前端的execve()函数命令非常相似。
File Copy测试
这项测试衡量文件数据从一个文件被传输到另外一个，使用大量的缓存。包括文件的读、写、复制测试，测试指标是一定时间内（默认是10秒）被重写、读、复制的字符数量。
Pipe Throughput（管道吞吐）测试
pipe是简单的进程之间的通讯。管道吞吐测试是测试在一秒钟一个进程写512比特到一个管道中并且读回来的次
数。管道吞吐测试和实际编程有差距。
Pipe-based Context Switching （基于管道的上下文交互）测试
这项测试衡量两个进程通过管道交换和整数倍的增加吞吐的次数。基于管道的上下文切换和真实程序很类似。测试程序产生一个双向管道通讯的子线程。
Process Creation(进程创建)测试
这项测试衡量一个进程能产生子线程并且立即退出的次数。新进程真的创建进程阻塞和内存占用，所以测试程序直接使用内存带宽。这项测试用于典型的比较大量的操作系统进程创建操作。
Shell Scripts测试
shell脚本测试用于衡量在一分钟内，一个进程可以启动并停止shell脚本的次数，通常会测试1，2， 3， 4， 8 个shell脚本的共同拷贝，shell脚本是一套转化数据文件的脚本。
System Call Overhead （系统调用消耗）测试
这项测试衡量进入和离开系统内核的消耗，例如，系统调用的消耗。程序简单重复的执行getpid调用（返回调用的进程id）。消耗的指标是调用进入和离开内核的执行时间。
Graphical Tests（图形）测试
由"ubgears"程序组成，测试非常粗的2D和3D图形性能，尤其是3D测试非常有限。测试结果和硬件，系统合适的驱动关系很大。
