Given that the author works at a large company, that has millions of machines, and where any swap change has cost implications in the tens of millions pounds, I suspect the article is based on data, rather than vibes.
Swap is less critical now, and given that k8s has some pathological dislike of it (again I suspect based on vibes) I can see why people dont have it.
However when you are using close to 70% of your total ram, swap improves performance significantly. Also where I work, it also stop the OOM from killing my repo VFS layer when I'm compiling something.
> The core problem with swap is that nowadays you need gigabytes of swap to actually make a difference
It was always the case. but then a TB of disk isn't that expensive anymore.
