【测试工具】UnixBench 测试

一、UnixBench 简介

• UnixBench 原本叫做 BYTE UNIX benchmark suite。软件为 Unix 类的系统提供了一些基本的性能指标。通过不同的测试来测试系统不同方面的性能（2D，3D，CPU，内存等等）。这些测试的结果将和一些标准的系统来做比较，从而得出一些性能指数，比原始 的测试数据容容易理解。
• 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。
• UnixBench测试执行完大约需要10-30分钟。

1.1 UnixBench 测试项目

• Dhrystone 2 using register variables
• Double-Precision Whetstone
• Execl Throughput
• File Copy 1024 bufsize 2000 maxblocks
• File Copy 256 bufsize 500 maxblocks
• File Copy 4096 bufsize 8000 maxblocks
• Pipe Throughput
• Pipe-based Context Switching
• Process Creation
• System Call Overhead
• Shell Scripts

二、UnixBench 测试

2.1 获取UnixBench

• git clone https://github.com/kdlucas/byte-unixbench

2.2 编译

• cd byte-unixbench/UnixBench
• make

2.3 运行

• ./Run

三、测试结果

硬件龙芯平台

• 硬件ls3a6000+7a2000
• 系统loonnix20.5
