Thanks for such great explanation and the demonstration as well!

Hey thanks! Even two years later its relevant. I want to use zram for temporary. Because it will increase lifespan of SSD because they can only do so many overwrites. Browsing the internet pretty much chews up my SSD. It hasn't gone bad yet, but it will one day. I just hope it doesn't require SystemD because I prefer other init. Anyway thanks!

Oh yes! It's running perfectly in OpenRC. I suppose I should have known, being that zram runs at kernel level. Now when I surf the net, all temporary internet files go to a RAM drive which is A) Not eating up overwrites on my SSD B) very secure because if I turn off my PC all internet data is PURGED. My PC never swaps unless I use chat4all or stable diffusion, because my GPU is only 12 gig. And swapping slows down the last 20% or so of image generation. But I put the part of the drive that is used during generation of image/chat onto a zram RAM drive and now it is much faster and won't be overwriting my SSD every time. It's my GPU that swaps when 12 gigabytes video ram isn't enough, not the CPU, so having my PC swap to system RAM DRAMATICALLY sped up image and chat generation. (I have 32 gigs RAM) This zram is quite useful for conserving overwrites on SSDs. And zswap allowed me to use system RAM as a swap for the GPU. I could hug you right now. Thanks for helping improve the security and performance of my shit.

I had to disable zram swap because I experienced a strange issue where Firefox would load directly into it, even though I have 128 GB of RAM. Also, whenever the 4 GB swap got filled by Firefox, it would result in a hard crash.

@rustydust8648 Жыл бұрын

@@prashanthb6521 never mind you should disable it, it is a not the right way to go about setting up zram it doesnt allocate/reserve the space for zram imagine you have 16gb ram, and 8 gb is zram you will use 14gb ram without going to zram when full 16gb is filled up, it will try to store in zram, but zram will have to clean up some space in ram to exist as all 16 gb is filled, this creates a deadlock situation, it will make your pc freeze and for the record, yes i tested

It'll really good if you can go in-depth technically for each command and flags used in the profile as well. For example, at @9:29 this is asking for an (r)ead permission to the Downloads folder right? e.g. While you can use "ls" tool, but you still need to read the Downloads folder (i.e. allowing ls to read Downloads folder).
