zram has been "obsolete" for years, I don't know why people still reach for it. Linux supports proper memory compression in the form of zswap https://wiki.arch

- ChocolateGod 9mo agoBecause I'd rather compress ram when running low on memory rather than swapping to my disks. zram is also default on some distros (e.g. Fedora).
- homebrewer 9mo agoDid you read the link? Additional disk swap is optional, and if for some reason you would still like to have one, it's easy to disable writeback, using just the RAM. And even if one enables zswap and configures nothing else, compressing RAM and only swapping out to disk under extreme pressure is still the default behavior.
- kasabali 9mo ago> Additional disk swap is optional Where did you read that? My experience has been that not only in reality the pool size is limited by the amount of swap space you've allocated, it's also uncompressed again when offloaded there which is ridiculous when you think about it.
- RealStickman_ 9mo agoI didn't realize zswap also uses in-memory compression. It might be a combination of poor naming and zram being continuously popular.

- rascul 9mo agoIt is not obsolete. It's also useful for other things.
