Ouch. I have no problem using 16GB RAM

Chrome/Chromium and Firefox are absolute pigs. I finally tamed Firefox
ty setting it to drop all cache and other stuff upon exit, and then I
shut down all instances of Firefox every day.

I don't know how many VMs you run, but those eat up memory.

What the heck kind of editor requires 3-4GB RAM? That sounds crazy to
me. Why do you have a few dozen files open simultaneously?

Libreoffice is kind of a pig. Is there something else you can use? And
why a dozen or two simultaneous files open? This sounds like a workflow
nightmare. Do you mean one Libreoffice instance with 24 files open, or
a bunch of separate Libreoffices in VMs. If the latter, yeah, that's
going to burn a lot of RAM, even more than one instance with 24
documents.

Ohhhh, KDE. I call that Krash, Delay, Expand. See
http://troubleshooters.com/lpm/201202/201202.htm . I use OpenBox, which
is a low-RAM, just-the-facts window manager. On every machine I ever
used KDE, performance was bad and on lower RAM machines, things ground
to a halt.
Gnome and KDE are luxuries for folks with lightning fast processors and
huge quantities of RAM, who want their computers to perform like a 2015
computer with 4GB RAM.

I'm running a 2014 computer:
* AMD A6-6400K APU with Radeon(tm) HD Graphics (dual core)
- 3.1Ghz dualcore
* 16GB RAM
* Openbox with dmenu and UMENU2
With no browsers open, this machine is is snappy as hell. With firefox
set to dump cache upon exit, as long as I do reasonable housekeeping on
tabs, and prophylactically close all firefox instances at least once a
day, everything's pretty good.
That being said, this is a 2014 machine, so I'm soon buying a 3.6 Ghz 6
core (65 watt) with 64GB RAM. This will give me more latitude in
running Chromium, which I need for Jitsi, and allow me less stringent
housekeeping in Firefox.
