OK so the timings look OK

Does your system have a Intel Ethernet chip?

What are your ping times if you ping the 7I92?

Is there a terminal command with which I can display my network chip?

Those ping times look pretty bad...

You might try:

dmesg | grep -i eth

looks like i have the Intel chip

 

 

OK for Intel Ethernet chips, you must disable RX IRQ coalescing
This is typically done in the interfaces file

man hm2_eth

for instructions

Also you can try this temporary fix:

sudo ethtool -C eno1 rx-usecs 0

and then try the ping test / LinuxCNC again

(this fix will only last until you reboot)
