So why are THP enabled by default? I could understand if they were

And I don't understand why redis recommend a setting of never rather

Strange, they are disabled on 42.3.

On my Lenovo laptop with Leap42.3 and 8Gb memory, it is enabled.

I suppose that is disabled. This machine has 8 GiB, a desktop with 15.0

I obtain the same result on my small laptop, which has 4 GiB.
