isolate the last core with isolcpus
Disable coalescing if intel
Use dkms driver if realtek
Set CPU affinity for NIC interrupt to be same as the isolated core

Thanks Rod!

I have done all that already except using dkms driver. It is an Intel NIC (e1000e) not realtek... Now time will show if it is fixed :)

I suspect the next thing (that causes intermitent latency spikes) is energy efficient Ethernet (EEE) disable it.
Also set the governor to performance.

Es riecht stark nach zu hoher Latenz. Wie sind die Werte vom Base und Servo-thread?

Gegen eine hohe Latenz habe ich nun schon ganz viele Einstellungen gemacht (u.a. alles, was Rodw empfohlen hat, inkl. EEE), aber ich habe derzeit keine Zeit mal einen richtigen Test zu machen, oder die Latenz zu messen. Die Goldene Regel, immer nur eine Änderung zur Zeit zu machen, habe ich auch schon gebrochen ;-) Sobald ich Zeit für meine Fräse finde, melde ich mich mit den Ergebnissen!

Vielen Dank an alle!
