The  test is also with test was with web browser version of speed net not cli
or platform specific. But  the 800/800 on windows 11 was with same tool and
test site.

 The Pi 4B has a true gigabit Ethenet interface, and is close saturating the connection (900Mb/s+) to other local machines in both directions using the command line iperf tool.
 [The Pi 3B+ had gigabit Ethernet, but used the internal USB interface and so was limited to 300Mb/s, where as the 3B and all previous Pi's were 100Mb]
 However, if you use browser based speed page, these are heavily javascript laden which will put quite a load on a 1.4GHz 4 core chip with limited memory, and may well not reflect the fastest possible speed obtainable.

That is good information.
I used to ftp to one of my remote dark office server and transfer a few megabytes to /dev/null to get a decent speed analysis
You might find some file online and download it using curl etc.
Those web based speedometers were designed in the days of 5Mbps ADSL...
