Utilize iPerf3 on macOS for assessing network bandwidth and throughput.
iPerf3 serves as a tool designed to evaluate the efficiency of your Mac’s network performance. In this guide, discover how to seamlessly utilize it through the Terminal application on macOS.
Originally developed at the National Center for Supercomputing Applications (NCSA) at the University of Illinois, iPerf (often referred to merely as “iperf”) is a utility focused on memory usage and networking capabilities. It represents a fully compatible successor to Test TCP (ttcp), which was initiated by the U.S. Army’s Ballistic Research Lab around 1983 under DARPA funding.
This tool also has contemporary adaptations available for Windows and Linux platforms.
iPerf exists in three distinct versions, with iperf3 being introduced in 2014; however, it is not backward compatible with previous iterations. This version also integrates a developer library enabling its utilization within other applications.
Unlike its predecessors that employed multi-threading—allowing concurrent code execution across multiple CPUs—iperf3 operates on a single thread model, optimizing resource usage yet still delivering high performance levels.
The redesign of iperf3 was carried out by experts from the U.S Department of Energy’s Energy Sciences Network (ESN) alongside Lawrence Livermore National Laboratory in California with aims to enhance network analysis capabilities. ESN links various commercial labs and research facilities worldwide.
You can find the source code for iperf3 hosted on GitHub under esnet / iperf, while Robert McMahon’s original iperf2 codebase remains accessible via Sourceforge along with an extensive comparative table between Iperf2 & Iperf3 available there.
Key Features
Primarily functioning as a memory-to-memory measurement instrument, iperf3 is adept at quantifying not just router effectiveness but also storage capacities along with overall bandwidth testing needs. A notable advancement over version 2 is its provision of output results in JSON format.
All variants of iPerf necessitate both client and server components for effective evaluations; iperf3 employs both TCP as well as UDP protocols throughout testing phases closely resembling commands utilized in prior versions despite lacking backward compatibility mechanisms – an illustrative command chart published by ESN aids users transitioning between versions effectively!
Installing iPerf3 on macOS
<
The default configuration of mac OS does not encompass iperf by standard installation procedure.The most efficient method for installing this tool involves leveraging Homebrew package manager combined with their corresponding formula specifically tailored toward lperF Cline:
< p > After establishing Homebrew onto your system , launch Apple ’ s Terminal app nestled within Application folder found under Startup Disk . Simply enter following command :< / p >
< pre >< code > brew install iperfto
< p > Executed correctly , this will trigger autoscript installations reliant upon ancillary packages inherent within last command executed . Those additional downloads may include : < / p >
- cfnctl
< li> comrak
< li> gauth
< li> gghlci
< li > ramalama <- list others here>etc List entire included packages here# !< p > Validation confirming successful implementation may be conducted via typing into terminal interface :
