If you have another hdd load 2.8.2 and see if that helps. I've got computers that run perfect on Debian 10 but have major latency issue on 12.

Here is the output of the console:
But in this case the Spindle Drive is off and Axis-controler are in STO mode / Standby.
I still have my servothread set to 2ms.
In the .ini file there is P = 744.158356898348. Sometimes I read it should be adjustet?
Trying 2.8 Version could be possible. But the hdd is hard to access. Maybe it´s easyier to do an image of this version and reinstall 2.8.
Are there any options to see if it´s an EMI issue? Because I feel the errors are popping up more, when the spindle is on and changing speed etc.

To check for an EMI issue, you could monitor
hm2_7i76e.0.packet-error-total in the watch tab of
halshow to get an indication of how often packets
are dropped.
Also you might try pinning the Ethernet IRQ to the
last CPU (the one LinuxCNC uses for real time)
This requires that you isolate the last CPU with
an isolcpus statement in your grub file
(isolcpus=3 for a 4 core CPU for example)
And then pinning the Ethernet IRQ to that CPU
