    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...

    The CLI version is pretty good on FTTH - but not all the test sites round here can keep up.

    Is it not the case that the Pi uses USB to talk to the ethernet chip?

    Not the RPi 4. Gigabit Ethernet is baked into the SoC. There are also
    carrier boards for the Compute Module 4 (which uses the same SoC) that put a second GigE controller on the PCIe port. I have such a setup running as my home router (running OpenWRT), and it'll max out my cable-modem connection. I've seen inbound speeds through it up to about 600 Mbps.

    Maybe the software you are using needs more CPU power than the Pi 4 has
    to
    give if you want it to go faster?

    What software are you using on the Pi 4?

    Raspbian GNU/Linux 11 (bullseye)

    I have had issues trying to run proton-mail.
    Seems like the decryption just kills the CPU.

    That is the throughput I expected. I got iperf3 for my work laptop win11 and
    home pc rasppi. Unfortunately, cannot run on win 11 due to not having admin rights. But I found a iperf3 server in Charlotte, NC . I'm in Fayetteville, NC.

    Upload/Download tests with TCP show expected throughput approaching 900Mb/s.

    So it looks like it is performing, just not with the web based tool on the
    rp 4b :-(

    Thanks for your explanations.
