I assume I should get rid of most of the swap. I also read somewhere to increase… swappiness of zram?

    Those defaults sound pretty sensible. I have as much swap as I have RAM because I set things up to hibernate. I believe pop os has the swappiness set to 180 for using the zram.

        There’s some instructions here but basically:

        1. sudo apt install zram-config

        2. append to end of /etc/sysctl.conf:

          vm.swappiness = 180
          # disable swap readahead (since using zram swap)
          vm.page-cluster = 0 
          

          Can check these have been applied with cat /proc/sys/vm/page-cluster or .../swappiness

      If you have more than enough RAM isn’t the older suggested configuration of low swappiness + modest swap should be more performant than encouraging the system to swap more and paying the price of compression. EG if you are apt to use 8GB in normal usage 32-64GB are at this point relatively inexpensive.
