Interestingly, my 64GB desktop has 50GB available between free and caches, yet has 95MB of swap space used (out of 8GB zram). How can I tell which process is swapped out? Probably something which I haven't ever needed since I've booted the PC.
Modern software are just ridiculously hungry for memory that even many GB is not enough. This is just bad considering that we used to work with only GB of disk. I wish all software designs are frugal in resources.

[ 5.5 ms ] story [ 15.7 ms ] threadzram is cool, and I've noticed Fedora uses it out of the box. Much better than regular swap space on a disk.

But you can take a look at the smem command:
smem -s swap -r
