disable swap. Programs will crash instead, which may be more useful.

Uhm, no.

Anything what would request memory would just outright die, including even the most basic services.

Source: actually had a system without swap what would just die running `dnf update`. Or quietly die in a week or so if left unattended.

Swap isn’t unlimited, it just delays the inevitable and makes everything slow while doing it. A 4GB swap partition isn’t going to save you if you run your 32GB computer out of memory.

		Who the hell would set 4Gb swap for a 32Gb RAM machine in 2025? A guy with a decade old 64Gb SSD as the only drive in the system? > and makes everything slow while doing it It was so when the OS was on a HDD. Nowadays it's a PCIe device with 1 million IOPS. And five years ago fans of some fruit company run around singing praises on how good their brand new laptops worked with a mere 8Gb of RAM.

		It does help. It gives time for the kernel in this situation and also helps in general by allowing to defragment memory. You want to keep a small amount of swap space at all times.

Unless it's some sort of autonomous safety-related process, It's usually better for the process to die so I can just restart it.

Even if it was some sort of safety-related process that had to keep running no matter what, I would probably try to define/control the memory usage better so it wouldn't unexpectedly run orders of magnitude slower.

Programs, including the kernel

		I've never had that happen. It usually just kills user-space programs
