Hey all,

I keep seeing this on my server:

I also notice my Sabnzb and Speedtest docker containers get up to 2,5Gbps speed. And my qBT clients dont, I only get 1Gbps speed on there.

Not sure if related, just adding all info here.

I'm running an Asus B760M-A D4-CSM board with the built-in NIC RTL8125 (running the r8169 driver)

Could this be fixed by just installing the RTL8125 driver from the app store and adding the blocklist driver r8169 was my next question, so I did this and verified through lspci -k that my new driver is indeed r8125.

However I keep seeing the drops on the interface.

I have added both diagnostics (pre and post driver update)

The Realtek-NICs are known as "tricky" under Linux - personaly, i avoid Realtek and use only Intel or Aquantia.

You can try a "non Realtek" NIC (if you have a spare PCIe-Slot) and see if it gets better.

If 2,5GBit are ok for you, i recommend an Intel I226-T1 PCIe-Card.

For 10GBit, since 2019, i use an ASUS XG-C100C with an Aquantia AQC107 (v1) / AQC113 (v3) Chip.

That can be normal, especially with Realtek NICs, as long as you are not having actual issues, you can ignore
