Since the discovery of Spectre etc, OS's have implemented mitigaions, some of which have pretty heavy performance hits for certain type of tasks,
As I understand it these mitigations can be enabled/disabled.
In my use case of AHRL, I simply don't see any security issue as it runs included software as a single user, off a usb stick.
I do however want to use old , slow laptops, which need all the speed they can get.
So I would think that turning off the mitigations would be desirable, if it isn't already the default.
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:

HI Simon,
I'm not going to change any of the Ubuntu defaults in this area. If a user believes they need to change these settings, they are free to do so.
