So why are THP enabled by default? I could understand if they were set to madvise for example, but are they likely to make a huge difference on my 8 GB desktop?
And I don't understand why redis recommend a setting of never rather than madvise, if anybody has any thoughts on that?
Strange, they are disabled on 42.3. Apparently there is benefit to the decreasing the number of lookups, but the downside is on systems running databases or dealing with sparse data. I don't know whether this helps or hurts the normal user.
It hurts me regularly when I run VMware virtual machines on Leap 15. Then khugepaged and the VM utilize the assigned cpu cores 100% for a couple of seconds up to a minute. Therefor I disable THP, if I care for the performance of the VM.
You disable it in host or in guest?
