Zsawp is not Zram, which is a distant relative of the macOS on-the-fly compression I was talking about. Zram is buggy and still advised against regular use (https://www.reddit.com/r/AsahiLinux/comments/1i3mdrw/comment..., https://chrisdown.name/2026/03/24/zswap-vs-zram-when-to-use-...). Zsawp itself is enabled by default in Asahi.
Zram and Zsawp are mutually exclusive on Linux. On macOS, both concepts coexist – except macOS is able to compress individual memory pages (https://news.ycombinator.com/item?id=38300432) on the fly. Zram is a compressed RAM block device with a hard capacity limit.
There is really no comparison here at this point. macOS is vastly superior in that regard.
