zram is cool, and I've noticed Fedora uses it out of the box. Much better than regular swap space on a disk.

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.
- redis_mlc 5y agoSome services expect to find swap enabled but normally don't use it (like mysql around 2010), so I wouldn't worry about the 95 MB. But you can take a look at the smem command: smem -s swap -r https://www.cyberciti.biz/faq/linux-which-process-is-using-swap/ https://www.cyberciti.biz/faq/linux-which-process-is-using-s...
