From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Examples could be things like specific configuration defaults or general decision-making in leadership.

Thanks for the links! I updated my config from z3fold to zsmalloc and adjusted the vm.page-cluster to test these out.

Reading a bit more, I think when using large max_pool_percent (>30) with Zswap the two solutions are more similar than not. A crucial difference is what use-case is more acceptable since Zswap can cause unresponsiveness (and potential lockup) under high memory pressure. While Zram could result in an OOM crash in a similar worst-case scenario.

Oh I can tell you that zram will not result in an OOM that zswap would prevent:

I once ran into a bug when using foobar2000 with wine to convert my music library that resulted in an insanely high ram usage, like my 16 GIB ram was filled and then my 32 GIB zram was also filled and the PC froze.

I just went and edited my zram config to make my zram 48GIB and ran foobar again, it ended the conversion without issue kek. No idea wtf happened but whatever data was being written in memory was being compressed good by zRAM, like very few people would even use a swap partition or file that is more than 32 GIB to begin with.

I also tested running Zelda tears of the kingdom in yuzu using 4GiB of ram with a big zram and it worked, that game in yuzu is a ramhog and on windows people need 16 GiB of ram and they still max out their swapfile.

There is also a vid on yt titled zram vs windows pagefile where a user running endevour demostrates how zram can take a bunch of Minecraft mods while windows with the help its of pagefile cant
