I've recently upgraded my internet to fiber to get 1G.

I've moved some of my machines to ethernet connections, to gain
more speed. On my windows 11 machine I can get 800/900 Mbps. But on my Pi I'm
getting much slower speed.

Any ideas why, and if I could improve the throughput to the ethernet to take
advantage of the higher speed internet ?

Getting 203 down / 273 up this morning :-(

Better than what I got with my previous provider; but I should be able to do
even better.

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

A chain is only as strong as its weakest link: ping and traceroute will
reveal where it is

That's why I cant be arsed to go beyond 40Mbps. I seldom achieve that
download speed with remote sites

How did you test that?

I just plugged in my Pi 4, upgraded to current OS (bookworm) and ran iperf3 between the PI and my desktop PC - the PI gets consistent 949Mbps (in both directions).

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?

Speedtest.net. I'll get iperf and see what performance I have between hosts.

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...

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

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.

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.
