Did the ping times improve?

What is your servo thread period?

What is LinuxCNC's servo thread period?

If the ping times did not improve,  there is something preventing good
Ethernet latency. What is the host machine hardware?

Have you disabled all power management options in the BIOS?

You might try a longer servo thread period
