Everything is disabled in the BIOS, no energy management, no Hyper Threading.
The temperatures are good, but there is still a lot of room for improvement.
There are always only peaks in an interval of about 1 minute that I see when I reset the latency test.
I still have an idea what I can try.

My idea was to pull out the USB to LAN adapter and then run the test again. At first it looked good, but after 15 minutes the value jumped up again, too high.
I have to wait for the new hardware.
No idea what else I can do. I don't feel like it anymore either.

So, new hardware arrived and I reinstalled everything.
Here are the current latency values: (During the test, YouTube videos were playing and I was surfing the net.)
and the PING results:

[/code]
Is this ok or can it be better?
I have worked through the instructions.

If the PC has a Intel MAC, you should disable IRQ coalescing
as described in the hm2_eth manual page
(and verify that its off with ethtool -c eno1)
replace eno1 with your ethernet device name if its different

It looks fine.
Did you test without isolcpu ? I really hate knee-capping hardware without a really good reason, so i never used it.

Is that what you mean?

No I have not. Should I do that?

OK so not Intel Ethernet hardware
Yes, the network card where the mesa card is attached is an Intel card. The onboard one for the home network is a Realtek one.
