Linux系统信息/IO读写/下载速度一键测试脚本bench.sh

2021-02-10 22:03:39  阅读：268  来源： 互联网

标签：下载速度 PLAIN echo sh awk && print bench size


目前一键测试脚本bench.sh已经非常成熟，你看到过的很多VPS服务器评测可能都是使用此脚本进行系统信息、IO读写、下载速度测试。bench.sh几乎支持所有Linux发行版系统的带宽、IO测试和服务器基本信息检测。

脚本使用命令

命令1：

yum -y install wget
wget -qO- bench.sh | bash

或者

curl -Lso- bench.sh | bash

命令2：

yum -y install wget
wget -qO- 86.re/bench.sh | bash

脚本使用小结

bench.sh使用非常简单。基本支持所有的Linux系统，而且测试结果呈现出来非常美观。使用此脚本可以一目了然的知道当前测试的各种系统信息、IO读写情况、全球下载速度测试。脚本的IO读写测试，采用三次读写测试后取平均值；下载测速是采用全球多处知名数据中心进行测试，并且还支持IPv6下载测速。如果再配合 unixbench.sh 脚本测试，即可全面测试 VPS 的性能。
