I have 64GB of RAM and 16GB of swap. Swap is small enough it can't get really out of hand.

I have memories from like 20 years ago that even when I had plenty of RAM, and plenty of it was free, I would get random OOM killer events relatively regularly. Adding just a tiny bit of swap made that stop happening.

I'm like 90% sure at this point it's just a stupid superstition I carry. But I'm not gonna stop doing it even though it is stupid.

Same here, though I settled on 32GB of swap because I have a 4TB SSD (caught a good sale on a Samsung EVO SSD at Newegg). But whenever I run `top`, I constantly see:

    MiB Swap:  32768.0 total,  32768.0 free,      0.0 used.

I could safely get away with 4GB of swap, and see no difference.
