In my production systems, and in my home systems, and in my gaming computers, I turn swap off. There’s no good reason to wear out disc writes. In production systems, I’d rather have something fail hard, then get slower and slower and slower falling behind.

Quite frankly, there’s no good reason to have swap on anymore, memory is huge. Most programs don’t need as much as they use. You can set memory pressure in systemd, telling programs to reduce their usage, and giving them individual hard cutoffs, so something like Prometheus can’t take down your whole system just because it’s got a memory leak.

oh yeah, it does that!

Get a ai agent, run it on your server as a un privileged user and ask it to do a security audit for you, delete the account after. If you want to get fancy make a new VM and give it root and ask it to probe your production host.

Everyone’s advice here is great, but you need to test your config and systems for gaps.

Works a treat for me!

But 100% is a big ask. There are always things to improve or fix
