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.

20gb ram, 10gb zram, 10gb swap, default values. What should I change? (lemmy.world)

I assume I should get rid of most of the swap. I also read somewhere to increase... swappiness of zram?

Those defaults sound pretty sensible. I have as much swap as I have RAM because I set things up to hibernate. I believe pop os has the swappiness set to 180 for using the zram.

Should I lower swap? How do I change the swappiness?

There's some instructions here but basically:

sudo apt install zram-config
append to end of /etc/sysctl.conf:
```
vm.swappiness = 180
# disable swap readahead (since using zram swap)
vm.page-cluster = 0 
```
Can check these have been applied with cat /proc/sys/vm/page-cluster or .../swappiness

Would these settings be the same if I used the same amount of swap?
