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.

My workstation has 48 GB RAM with 50% allocation allowed to zram, no disk swapping. It works just fine. Once I use up the majority of my RAM, it kicks in the same way it would on any other system with less RAM.
Shouldn't total ram amount always be powers of 2 (forgot the reason exactly) ? It sounds like 32 +16 wouldn't be ideal ? I remember that from my early days, but maybe it has changed ?
Not according to the chrisdown blog post above.
What about it? I see it kicking in at least 10 GB before my RAM is full and I haven't noticed any fundamental differences between how zram works on my 48 GB workstation and my 8 GB devices. Maybe I've never had a workload that filled all 48 GB + extra zram capacity, but it's never given me an issue.
