Are you in the US? I would try to run tests to the same place to establish consistency in your data (openspeedtest.com). Source: 12 months ago

Hmm I get 57 down and 28 up using openspeedtest.com. Maybe all these speed test sites aren't good. Source: about 1 year ago

Playing around with the ER8411 with 5Gbps internet and I am able to get download speeds of 4.9~5.0Gbps but no matter which site I test with; fast.com, wifiman.com, openspeedtest.com, or speedtest.net I am unable to get beyond 1Gbps upload. Source: about 1 year ago

Does it affect traffic that's only inside your LAN as well? I use https://openspeedtest.com for doing local speedtests, in case you need a way to test that. Source: about 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: about 2 years ago
