in Three Reasons Why You Should Not Use iPerf3 on Windows on Apr 23 2024 12:19 PM
Sure, for MSFT only then MSFT tools are fine. Most networks now are a mix requiring tools that run on all platforms and systems. Iperf3 is designed for capacity tests and does say use iperf2. Yet most still use Iperf3 because 3 is larger than 2 and they don't understand the technical differences. Yo...

@rjmcmahon Please keep in mind that I am in support, so the article is support slanted. From a Microsoft supportability perspective, we need internally trusted tools like ntttcp and ctsTraffic that we (Microsoft support) can use for troubleshooting purposes when addressing networking issues related ...

@JamesKehr Hi James, It's not in the interests for a platform vendor to supply the tool to test their platform, particularly if that tool is platform or os specific. It has to be broadly accepted as reliable, open & transparent to code changes, and vendor independent. Iperf 2 goes back like 15 years...

Thanks again, @rjmcmahon ! In true Microsoft fashion, we have a separate tool just for latency called Latte. https://github.com/microsoft/latte https://learn.microsoft.com/en-us/azure/virtual-network/virtual-network-test-latency?tabs=windows

@JamesKehrYeah, it's a common misconception that a bigger number means better. In iperf's case, the number indicates different development teams with different goals. Iperf 3 is a misnomer as it's a not a follow on to the original iperf. Iperf 2 is based from the original code.I'd suggest trying ipe...
