This comment is how I learned about zram. Just one question, when is it used?

[–] AProfessional@lemmy.world 4 points 3 months ago* (last edited 3 months ago)

Fedora enables it on all systems with <4GB (maybe a bit less I forget). It’s trivial to enable/disable it and see if its helpful for your usage.

Yep. I just looked it up.

I assumed it was like windows page file but it's ramdisk.

Depends on config, ArchWiki recommends optmizing some sysctl values to take advantage of it

it generally starts kicking in after >60% RAM usage even with this config
