There has been no increase in computing power in the Free World.
I expect that Amin chooses these older machines

for the same reason I choose them: the FSF recommends them, because newer
processors have back doors.  Intel processors newer than that contain
the "Management Engine" back door and can't start up without it.

So please, everyone, take care to maintain good performance on these
older machines.

Is it possible, to restore most of the lost peformance by deactivating
some new features?
