Wow! How long did You run the latency test? Did You try to put some load to PC?

Well, if You will open /boot/grub/grub.cfg filem You will see this
line at the very top:

# DO NOT EDIT THIS FILE

I really suggest following this kind advice. Especially if it is
written with capital letters :))

My googling results tell, that You should edit /etc/default/grub
For that You will need root privileges. You can do that by running in
terminal this command:
sudo gedit

Text editor will be opened, click "open" and find the file.

There is a line:
GRUB_CMDLINE_LINUX=" "

Change it to:
GRUB_CMDLINE_LINUX="isolcpus=1"

Save the document, close text editor.
To apply changes, run in terminal:
sudo update-grub
