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.

Let me use my Raspberry Pi 3b as a practical example of what @vithigar@lemmy.ca was explaining. I run PiHole + Unbound on the Raspberry Pi 3b, with 1GB of ram. The main killer for a little Pi 3b is reading and writing to the SD card. We want to avoid that as much as possible. Block lists get updated weekly, so that's no big deal, but there is still a lot of traffic information that is being kept track of. The solution is to load all of that into zram. As you can imagine, on a slow and resource constrained system like a Pi 3b, any performance enhancement has a huge impact. A 452x performance increase over ZRAM on a system that mostly lives on ZRAM is massive.
I am not entirely sure about this but I imagine that this is also massive news for live operating systems like Tails and Kali Live.
