Not good

What host hardware do you have (CPU and Ethernet chip)?
 

NUC Intel N5105 2.00 Gz
Realtek PCI GBE

Typically the Realtek MAC requires the DKMS driver for usable latency.

Not sure which thread is the best on this but searching the forum for "DKMS"
will find a thread that shows the Realtek DKMS driver installation details.

Hallo
Realtek DKMS-Treiber. installiert.
Test

rtt min/avg/max/mdev = 0.085/0.161/3.281/0.042 ms

rtt min/avg/max/mdev = 0.085/0.161/3.281/0.042 ms

is better but still not good

Take a look at this thread, especially the kernel command line (setup with grub)
