UnixBench是一款开源的用于测试Unix、BSD、Linux系统基本性能的工具，比较通用于Linux系统VPS性能测试，主要测试项目有：系统调用、读写、进程、图形化测试、2D、3D、管道、运算、C库等系统基准性能提供测试数据。关于如何使用UnixBench为Linux系统VPS进行跑分测试，主机玖玖曾在如何对VPS进行性能测试及UnixBench跑分工具使用教程文章当中做过相关介绍，在此文章当中为大家介绍一个由@秋水逸冰大佬制作的UnixBench一键跑分测试脚本，使用非常简单，下面简单的几段命令即可实现一键跑分测试。
一、脚本命令
如果你想使用UnixBench测试你的服务器性能，请使用SSH工具连接你的服务器后执行下面命令。脚本默认使用UnixBench5.1.3版本，因为大多VPS都没有显卡或者是集成显卡，不需要进行图像性能测试，所以作者注释了关于graphic的测试项。此脚本运行测试时间大约10-30分钟，跑分结束后得分越高性能越好。
wget --no-check-certificate https://github.com/teddysun/across/raw/master/unixbench.sh chmod +x unixbench.sh ./unixbench.sh
主机玖玖备用命令：
wget --no-check-certificate https://github.com/zhuji999/unixbench/blob/master/unixbench.sh chmod +x unixbench.sh ./unixbench.sh
二、测试效果
