Ethr Build Status

Ethr is a cross platform network performance measurement tool written in golang. The goal of this project is to provide a native tool for network performance measurements of bandwidth, connections/s, packets/s, latency, loss & jitter, across multiple protocols such as TCP, UDP, HTTP, HTTPS, and across multiple platforms such as Windows, Linux and other Unix systems.

Ethr server in action

Ethr takes inspiration from existing open source network performance tools and builds upon those ideas. It is very similar to iPerf3 for bandwidth measurements for TCP. iPerf3 has many more options for doing bandwidth measurements such as throttled testing, richer feature set, while Ethr has support for multiple threads, the ability to scale to 1024 or even higher connections, multiple clients to a single server etc. It is similar to latte on Windows or sockperf on Linux for doing latency measurements.

Ethr is natively cross platform, thanks to golang, as compared to compiling via an abstraction layer like cygwin that may limit functionality. It hopes to unify performance measurement by combining the functionality of tools like iPerf3, ntttcp, psping, sockperf, and latte and offering a single tool across multiple platforms.

Ethr provides more test measurements as compared to other tools, e.g. it provides measurements for connections/s, packets/s and latency, all in a single tool. In the future, there are plans to add more features (hoping for others to contribute) as well as more protocol support to make it a comprehensive tool for network performance measurements.

Installation

Note: go version 1.10 or higher is required building it from the source.

Building from Source

git clone https://github.com/Microsoft/ethr.git
cd ethr
dep ensure -v
go build

Docker

Build image using command:

docker build -t microsoft/ethr .

Make binary:

Linux

docker run -e GOOS=linux -v $(pwd):/out microsoft/ethr make build-docker

Windows

docker run -e BINARY_NAME=ethr.exe -e GOOS=windows -v $(pwd):/out microsoft/ethr make build-docker

OS X

docker run -e BINARY_NAME=ethr -e GOOS=darwin -v $(pwd):/out microsoft/ethr make build-docker

Using go get

go get github.com/Microsoft/ethr

Using ArchLinux AUR

Assuming you are using yay (https://github.com/Jguer/yay):

yay -S ethr

Usage

Simple Usage

Help:

ethr -h

Server:

ethr -s

Server with Text UI:

ethr -s -ui

Client:

ethr -c <server ip>

Example:

// Start server
ethr -s

// Start client for default (bandwidth) test measurement using 1 thread
ethr -c localhost

// Start connections/s test using 64 threads
ethr -c localhost -t c -n 64

Complete Command Line

Common Parameters

-h                        Help
-no                       Disable logging to a file
-o <filename>             Log to the file specified by filename.
                          By default Ethr logs to ./ethrs.log for server & ./ethrc.log for client mode
-debug                    Log debug output

Server Parameters

-s                        Server mode
-ui                       Display text UI

Client Parameters

-c <server>                   Client mode, connect to name or IP specified by server
-t <b|c|p|l>                  Test to be done, b: bandwidth, c: connections/s, p: packets/s, l: latency
                              Default is bandwidth test
-p <tcp|udp|http|https|icmp>  Protocol to use, default is TCP
-n <number>                   Number of sessions/threads to use
-l <number>                   Buffer size to use for each request
-i <number>                   Number of iterations for latency test
