I would have thought that i3wm would use a lot less memory, given how basic it is.

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.

Given your observation, I'm guessing you have not used i3wm very much. i3 is extremely flexible and powerful. But as with most Window Managers, i3wm is geared towards those who prefer to build a highly customized environment. If you haven't already, this is a good read. https://i3wm.org/
It's interesting how close they are to one another. I don't understand why there is a Dropbox column and didn't see it mentioned anywhere else. Another question I have is how much RAM the system has in total, as that seems to affect consumption.
Thank you for noticing my omission. I added the following: NB.: Dropbox is shown because it runs at login and is a large contaminant in terms of memory utilization on each window manager (setup). If you do NOT use Dropbox you should expect your idle memory use to be lower than my total by some 600MB.
That makes way more sense. I remember plasma idling around 1.4 GiB back when I was running Arch with 16 GB of RAM. Although right now on my Kubuntu machine at work, I'm using 3.0 / 110 GiB just being on the desktop.
Another factor impacting memory significantly is the kernel used. My liquorix kernel "updated" this morning and I am using 200MB less memory than yesterday; it must be my lucky day. 😜
