Hello guys,
I confirm that the cleanup is exactly the same using all removing profile.
The only difference is the number of cpu threads used, which depends on your CPU : the faster it is, the more CPU threads it uses to increase speed. So, of course the more recent CPU will always be faster than the older, in term of removing efficiency. And as KrX said, the used RAM is also increased with insane profile without creating troubles with your system.
And there are no troubles to use insane removing profile in an older cpu, to increase the speed (but it always depends on your cpu speed).
