iperf VS LAN Speed Test

Just some clarification: IPerf 2 is different from the iperf3 found at https://github.com/esnet/iperf. - Source: Hacker News / 6 days ago

Network - network throughput (both incoming and outgoing) is tested using iperf3 on several geographically diverse public iperf servers. Source: over 1 year ago

File transfer using iperf3 over Tailscale. I noticed that the bandwidth to my home computer (on a 500/500 fiber connection) was higher than with speedtest.net. For the first few days I was getting downloads and uploads of 28Mbps (+/- std dev of 6Mbps) and 150ms latency (+/- 35ms). After somewhere around 100GB total transfer (maybe half of that over Tailscale), it is now downloading and uploading at 10Mbps (+/-... Source: about 2 years ago

I can add to this. I have two mini self contained projects to create multiarch static bins of mtr and iperf3 for general usage. Source: almost 3 years ago

To get these numbers I am using lan speedtest, and have run multiple tests with multiple packetsizes between devices on the network. I seem to get faster speeds with larger packet sizes. Source: 5 months ago

As far as stress testing i/o and network, I'm unsure, never had to test it. I've used Lan Speed Test by Totusoft to narrow down degraded network performance between devices on a LAN to a smaller area of troubleshooting. Https://totusoft.com/lanspeed. Source: about 1 year ago

How are you testing your connection? For internet speeds use speedtest.net I use https://totusoft.com/lanspeed to test speeds for my LAN. Source: over 1 year ago

After a quick search and a test, you can also use This program to test the speed between your computer and your LAN. This can help you to determine if the problem lies between your computer and the modem, or the modem to the internet. Source: over 1 year ago

A great way to test raw throughput and read/write speeds on your home network is to use Lan Speed Test: https://totusoft.com/lanspeed. Source: over 1 year ago
