I have been setting up Zram, Swap, Swappiness and EasyOOM daemon on 16gb ram boxes, or lower. Someone asked me about 32gb of ram, or more, and I’m unsure. Wondering if others have experimented with this!

    Why do you think 32GiB is special compared to 16GiB?
    And wtf is EasyOOM?

    You maximize the usefulness of zram by actually increasing sappiness, and giving zram devices high priority. e.g.

    sysctl vm.swappiness=100

for i in {1..8}; do
  swapon /dev/zram${i} -p 32767
done

    Then you enable other swap devices with lower priority.

    This is the way regardless of how much RAM you have. I mean, it may be pointless if you never ever exceed, let’s say 10/32GiB (including caching). But it still wouldn’t be harmful in any way.
