# p7zip

p7zip 测试是用于测试系统解压性能,通过数据直观评估性能,以下是运行 7pzip 测试的操作步骤

## 安装 7zip

首先需要在 RevyOS 中 安装 p7zip

```
debian@lpi4a:~/Desktop$ sudo apt update
debian@lpi4a:~/Desktop$ sudo apt install p7zip-full
```

## 执行性能测试

进行 p7zip 测试需要在终端中输入以下命令来执行:

```
debian@lpi4a:~/Desktop$ 7z b
```

系统会开始进行测试然后输出性能数据。

通过以上步骤,可以在 RevyOS 上安装并测试 7zip 的性能。

以下是测试结果参考,使用镜像版本为[RevyOS20231210](https://mirror.iscas.ac.cn/revyos/extra/images/lpi4a/20231210/)16g版本
