swappiness, SSD health, SWAP, common missunderstanding, change in the algo

[Nikolai Safronov]

Hey! Love your work.
You might want to go down the swappiness value rabbit hole:
https://bbs.archlinux.org/viewtopic.php?id=271192
https://chrisdown.name/2018/01/02/in-defence-of-swap.html

Two main takeaways:

- "The best practice for SSD is having swappiness around 100."

- SSD is impossible to "shield" from swap writes - even with a zero swap, as in a crunch the pages would be written to disk anyway.

Best, Nick

Hi Nikolai,

Well, opinions differ. As do use cases. For the time being, I think my current advice (swappiness of 25) is the best compromise....

Regards, Pjotr.
