This is a followup to my recent post as well as other post in the Forum. I am a noob at this, both zram and zswap. I have very vague ideas on both of them. All I know is that zram has to be installed as package on EOS, whil zswap is practically baked into almost all the Linux Kernels out there. Eve…

[image] mbod: You asked me multiple times about proof regarding the zswap/zram performance. I gave it to you with links. You even gave it to yourself with the link you shared in your first post. Thats it. The article I linked to actually doesn’t provide any conclusion as to which is “better”.…

[image] Irregular: The article I linked to actually doesn’t provide any conclusion as to which is “better”. It says it is “use case” dependent. And there is your answer, right there

[image] wolfn: +1 In the Arch-wiki they linked an article: link There are so many aspects, I think you will never hit the bulls eye… And one aspect I am missing totally here: afaik all Arch-based (or systend?) systems use half of the available ram for a ramdisk with /tmp & some more inside to…

[image] Archie1: stress-ng is part of which package? It is not installed in my EOS system. stress-ng is its own package which is not installed by default: extra/stress-ng 0.19.05-1 [0 B 18.62 MiB] Software to stress test a computer system in various selectable ways

[image] Archie1: What surprised me was when @mbod clarified that Fedora was using ZRAM equal to physical RAM and that too Out-of-the-box. I might be one of the very few distros that do this. Yes, that surprised me too when I tried Fedora on my laptop. This is even going so far that Fedora lap…

Here we go. We also got a honorable mention to this thread. :rofl: [image] Debunking zswap and zram myths zswap and zram are fundamentally different approaches with different philosophies. If in doubt, use zswap.

Now I’m confused. Lets wait for other to chime in :sweat_smile:

Yes this thread is mentioned in the section, “LRU inversion”. I did not realize that EndeavourOS was one of the distros that gurus and experts look at. I always assumed that Arch/Debian/Fedora/Suse were the places where all the actions took place. It is nice to know that Endeavour is among the top t…

[image] Schlaefer: We also got a honorable mention to this thread. :rofl: Well, is it really honorable that the following zram configuration is used as an negative example ? The article essentially explains the issue with such a configuration of the zram But such users have unwittingly cr…

That’s a problem with this setup, if you spill over to disk it will run the hot part on the slow disk. But that’s up to the user to decide. Maybe they know, maybe they monitor their zram usage, they never exceed it, and they just have it for a peace of mind/hibernation. Some people have strong opin…

Zram vs zswap. Why choose one over the other
