在本教程中，我们将看到另一个称为UnixBench的基准测试套件。
它是原始的BYTE UNIX基准测试套件，多年来被许多人更新和修订。
该工具的主要目的是提供类Unix操作系统性能的基本指标。
运行单个或者多个任务时，可以使用UnixBench评估系统的性能。
请注意，这是系统基准测试工具，而不仅仅是CPU，内存或者磁盘基准测试工具。
结果不仅取决于硬件，还取决于操作系统，库，甚至编译器。

Unixbench将在系统上进行以下基准测试。

• Dhrystone-用于衡量和比较计算机的性能。
• 油石-用于测量浮点运算的速度和效率。
• execl吞吐量-用于测量每秒可以执行的execl调用的数量。
• 文件复制-用于测量数据从一个文件传输到另一个文件的速率。
• 管道吞吐量-进程可以向管道写入512字节并回读它们的次数（每秒）。
• 基于管道的上下文切换-用于测量两个进程可以通过管道交换递增整数的次数。
• 进程创建-用于衡量进程可以分叉并收获立即退出的子级的次数。
• Shell脚本-用于衡量进程每分钟可以启动和获取一组八个Shell脚本并发副本的次数，其中Shell脚本将一系列转换应用于数据文件。
• 系统调用开销-用于估计进入和离开操作系统内核的成本。
• 图形测试-用于提供系统2D和3D图形性能的概念。

在Linux上安装和使用Unixbench

UnixBench在AUR中可用，因此我们可以使用AUR帮助程序将其安装在Arch Linux及其派生产品（如Manjaro Linux，Antergos）上。

使用Yay：

$yay -S unixbench

在其他Linux发行版中，我们需要手动编译并安装UnixBench，如下所示。

在CentOS，RHEL，Fedora上：

$sudo yum -y install gcc gcc-c++ make libXext-devel perl perl-Time-HiRes git

$sudo yum -y groupinstall "Development Tools"

$sudo yum -y install libX11-devel mesa-libGL-devel perl-Time-HiRes

在Debian，Ubuntu和Linux Mint上：

$sudo apt-get install libx11-dev libgl1-mesa-dev libxext-dev perl perl-modules make git

安装必要的准备工作后，git使用以下命令克隆UnixBench存储库：

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

转到unixbench目录：

$cd byte-unixbench/UnixBench/

然后，运行以下命令开始对系统进行基准测试。

$./Run

如果已在Arch Linux上从AUR安装了UnixBench，请运行以下命令将其启动。

$ubench
