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.

Zram usually has a very high compression ratio - around 4:1 for lz4 and 6:1 for zstd. You can set zram to 40-50 GB. It will still use less than 1/2 of your ram.
Zram has an option to write poorly compressible data to the disk instead of storing it in the ram. I would split the swap partition - 3 GB for zram writeback and rest for ordinary swap.
Oh, I think I might have thought zram was similar to swap, I didn't realize it takes up ram. Is there a way to see how much ram it's using? What do you think I should set my zram amount to(and how do I change the zram amount, I'm using zram-config)
Zram is basically a compressed swap device located in your ram. You can check the usage by running zramctl.
I would recommend setting mem_limit to 10 GB or disk_size to 40GB and algorithm to lz4.

This link says that configuration is stored in a file that doesn't exist, should I make it?
Which part is the usage?![](https://lemmy.world/pictrs/image/55eab1d5-1f27-4769-bf47-614ef1e2d78b.png)
