概述

用于计算服务器出入口实际带宽速率，用于统计服务器网络测速统计。

脚本功能

该脚本会根据当前服务器内存剩余空间判断生成约为1.5G临时文件，并提交至指定的url地址进行出口带宽占用。通过检查默认出入口网卡流量数值来判断出入口带宽网络速率。

执行效果

本脚本不适宜在生产或已部署服务的服务器上运行，可能会因CPU&内存占用过高导致其他服务被系统杀死

[root@cloud-node1 ~]# bash test.sh
当前默认网卡 ens32 上行测速将开始，等待10s...
当前默认网卡 ens32 下行测速将开始，等待10s...
当前默认网卡 ens32 物理速率为: 1000Mb/s ,实际测试流量下行速率约为: 917 Mbps/s,上行速率约为: 98 Mbps/s
当前默认网卡 ens32 物理速率为: 1000Mb/s ,实际测试流量下行格式化速率约为: 114.74 MB/s,出口流量格式化速率约为: 12.29 MB/s
