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: 6 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

I think such a tool is fairly straightforward to develop with iperf 2 as the underlying src/sink. The man page has new features including start times & permit keys. Active, low duty-cycle, low impact telemetry has been a goal. The idea is that someone else would develop a web app and host public servers. As an iperf 2 maintainer, I'm trying to remain arm's length from such products but I do think the industry... Source: over 1 year ago

Iperf 2 can help and has many new tests including one way delay, low duty cycle burst, tcp bouncback, etc. More on the man page. OWD does required clock sync. Source: over 1 year ago

A bit of a tangent, but there are a lot of new features in iperf 2, much are around latency or one way delay (OWD). Many times these days it's latency that affects the quality of experience to end users. Source: almost 2 years ago
