概述
Ethr 是一个用 golang 编写的跨平台网络性能测量工具。该项目的目标是提供一个本地工具，用于跨 tcp 、 UDP 、HTTP、 HTTPS 等多种协议以及跨多个平台的带宽、连接/秒、数据包/秒、延迟、丢失和抖动的全面网络性能测量; Ethr 支持多线程，这允许它扩展到 1024 甚至更多的连接数，多个客户端与单个服务器通信等; 用于延迟测量，它类似于 Windows 上的 latte 或 Linux 上的 sockperf
1、ethr 二进制 安装
wget
unzip ethr_linux.zip
mv ethr /usr/local/bin && chmod +x ethr
2、ethr 命令行常见选项
-t 指定测试类型, 取值包括 b 带宽 c 每秒连接数 p 每秒包数 l 延迟、损耗和抖动 pi Ping 丢失和延迟
-x 指定适用于到目标站点的 网络测试
-n 并发会话/线程数, 0 设置为当前 cpu 数
-d 测试时长, 0 不限时
-p 指定测试时的协议类型, 取值 tcp、udp 等
