execution bug in older Intel and AMD silicon, but the fix wasn't

Unless anyone else ever accesses your PC in any way

terse make-linux-fast-again.com useful. The site is a little dated – you 
only need all of the switches if you're running a kernel older than 
version 5.1.13. These days, just the last one is enough. Add it to the 
end of the kernel line in /etc/default/grub, run update-grub and reboot.

Note Cautions.
Really.
