Turn Off Software Mitigations for Intel Processor Vulnerabilities on Ubuntu Linux

Only apply this to a computer that is not online, or is behind a firewall and running trusted software. Older processors may have increased performance after applying this change to GRUB.

Steps to Turn Off Mitigations

1. Edit the GRUB configuration:

sudo nano /etc/default/grub

2. In the GRUB_CMDLINE_LINUX_DEFAULT line, add parameters like (mitigations=off):

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash mitigations=off"

3. Update GURB:

sudo update-grub

4. Reboot the computer.
