How much swap?
How much swap?
I've heard a lot of people say your swap should be 2x RAM.. but do I really need 32GB of swap?

There's people who make dumb arguments that go "but what if you run out of ram?" And then someone else says "I have enough ram" and then someone else goes "but what if you run out of ram?"
I have a small amount of swap, a few gigs, and enough memory for the application. Moreover I also have my swappiness set to 0 because I don't want stuff swapped out of memory. If I need more memory I need more memory.

I'm one of those people.

This is a nice read from a kernel developer responsible for memory management.

Hi there! Looks like you linked to a Lemmy community using an URL instead of its name, which doesn't work well for people on different instances. Try fixing it like this: !selfhosted@lemmy.world

I don't think swappiness has worked that way for a while now.

It does. I can vouch for it's behavior in practice. My servers basically sit with the swap file unused, which isn't the case when I set swappiness to a non-zedo value
