ZRAM is very efficiently compressing information in the RAM and creates a kind of the virtual SWAP device, which actualy do not takes physical space on yours SWAP partition. It comes with a tradeoff of the a little bit perfomance that’s being taken to compress and unpack data. but ZRAM is active by…

Would enabling ZRAM not slow down a system that already has more than enough ram, like I have 32gb of ram, Why would I need to enable ZRAM?

[image] VolantesMagus: 32gb of ram If you are not utilizing all your ram, you don’t need zram in the first place. However, if your ram usage is shooting past 32gb, then zram will help. Keep in mind, if you make the zram size too large, it will probably backfire under higher load.

So if I enable this, it will use all my ram as a compressed swap? Aproximately how much more ram space I will get out of this? 10%? Or more? I have 14 gigs, and I had situations where it wasn’t enough and the system slowed down a lot, even with a nvme ssd. But I guess, I will still need a regular s…

[image] MindTheGAAP: Btw do you have a YouTube channel where you did a video on zram? Yes. However an obligatory note : the config format has changed after I made the video. As usual, the new config too is “readable”. Rest of the steps remain same.

[image] mihalycsaba: Aproximately how much more ram space I will get out of this? 10%? Or more? You can set that in your ZRAM config. My systems with 8 GB or 16 GB RAM work well with 50% ZRAM size. No slowdowns. On my old desktop with a dual core processor and 4 GB RAM, I couldn’t go past 2…
