There is a nice way to get a good speed boost for your Ubuntu system, this disables a few security settings for your Intel CPU, this can reduce the security of your Linux system, but can speed up your CPU a small amount. These settings from https://make-linux-fast-again.com/ are very useful to provide this speed boost.
noibrs noibpb nopti nospectre_v2 nospectre_v1 l1tf=off nospec_store_bypass_disable no_stf_barrier mds=off tsx=on tsx_async_abort=off mitigations=off |
Edit the /etc/default/grub file as root and add this to the GRUB command line.
GRUB_CMDLINE_LINUX="noibrs noibpb nopti nospectre_v2 nospectre_v1 l1tf=off nospec_store_bypass_disable no_stf_barrier mds=off tsx=on tsx_async_abort=off mitigations=off" |
Then run sudo update-grub.
After a reboot, your Linux system should be a little faster, this disables some security settings for your Intel CPU, but this means you will have to take care running programs that you download off the Internet, which you should be anyway, this is just basic common sense practice.
Basic common sense isn’t turning off the things that protect you from a major CPU exploit…
There’s no doubt that this makes your Linux computer run faster, but even so much as connecting your computer to the internet after doing this would be astronomically stupid.
