Still many other problems.., furthermore, for latency problem, I hesitiate to update network card driver as my sources.list contents are a liitle bit different from what the links' information mentioned

Try setting isolcpus=1
I use grub-customizer to do this. It is installed on the linuxcnc ISO's

Did you disable stuff in BIOS?
