Story time : I couldn’t run VSCode with Chrome/Firefox open; sometimes, even Chrome alone would crash. JetBrains IDEs were very slow, and I was about to give up on EOS. Then I realized I had no swap…

[image] MarkMcCoskey: Even with only 40% of RAM used, I see that I’m also using 9% of Swap. From my experience a 1:2 ratio of “used RAM” vs cache is a healthy ratio for a properly speced desktop system. After that it should hit swap. Everything above 1:1 I consider memory starved. Not that yo…

My memory is maxed out at 128GB. My system was crashing due to running out of memory when running multiple instances of a Python data processing script, so I added 128GB of swap, and that took care of the problem. Since I’ve switched from zfs to btrfs for my large data stores, memory hasn’t been as…

Yes, in my experience zfs wants to put EVERYTHING in cache, quite aggressively.

Yes i get that it is helpful and sometimes needed but there are cases where it it doesn’t really affect daily use. But yes it can and does, and is a good idea to have some form and size of swap to alleviate any issues in that regard. I do agree that it makes sense to add some form of swap whether it…

I only see a swap coming! Isn’t that a paddle board? :grimacing:

[image] ricklinux: If your system never uses more than 75 or 85% of your RAM, then you don’t need a swap file in my opinion. How did you get those numbers? It’s completely wrong, btw. :rofl:

Almost quit EOS because I forgot to set up a swap

I know that it was recommended to disable zswap if using zram. See:

However, I don’t find any reference to this in ArchWiki anymore.
