Just to be super nerdy, here’s an amazingly well-written article on the subject from someone with a lot of credibility: https://chrisdown.name/2026/03/24/zswap-vs-zram-when-to-use-what.html
tldr; prefer zswap
What a load of bull. Zram is so much more useful. That guy does not even know you can set up a fallback device for zram. Don’t trust any fool with a blog. Probably written and “researched” with ChatGPT.
“That guy” works full time as a kernel developer on the Linux memory management.
You should read the article. It has a section specifically on using a zram fallback device and how its performance compares to a similar zswap setup.
